1. INTRODUCTION

This document describes the IBIS-L system (Image By Interferometric Survey -L), with

particular reference to the concepts the user should learn before starting to use this device.

Therefore we recommend to read the entire document before starting up the system.

If technical assistance is required, please use the contact numbers provided on page 3 of

this manual.

1.1 Aim

Reading this document will provide the operator with all the necessary knowledge to

install and maintain the IBIS-L system. In particular, it provides a step by step procedure

for installation of the system, information for the safe use of the system and instructions

for general maintenance.

1.2 Field of application

This document applies to the installation of the IBIS system in -L configuration and its

use in the field for monitoring of quasi static phenomena.

1.3 Authorisation for use – national restriction

European countries

IBIS-L system has been classified from the CEPT Administrations as SRD – Short Range

Device - i.e. a device that doesn’t cause interference to other systems operating in the

same frequency band. IBIS-L has so been included (as Ground Based SAR) in the

ERC/REC 70-03 that defines the SRD equipment.

For Ku band system

In the meanwhile that all the European countries update their national frequency

allocation table applying the new recommendation, currently the use of IBIS-L system

outside a laboratory can be still subject to authorisation by the Competent Ministry of the

country where the system should be used. Please refer to the Competent Ministry of the

country where the system should be used to know whether there is still the need of an

authorisation or not.

For X band system

Almost all the European countries have applied the ERC/REC 70-03 for the X band

system. Please refer to the Competent Ministry of the country where the system should be

used to know if there are some limitations in the use of X band IBIS-L equipment or not.

2. OVERVIEW

This manual describes the operations that the user must perform to set up and use the

IBIS-L system.

2.1 How to use this manual

This manual consists of the following chapters:

• Chapter 1 - Introduction

• Chapter 2 - Overview

• Chapter 3 - IBIS-L system hardware configuration

• Chapter 4 - IBIS-L system installation procedure

• Chapter 5 - First start up

• Chapter 6 - Useful Tips

• Chapter 7 - Maintenance

• Appendix A - Technical specifications

• Appendix B - Elements of radar technology

2.2 General description

The IBIS-L system is designed to remotely measure slow displacements with an accuracy

as great as a tenth of a millimetre. The IBIS-L system is particularly suitable for terrain

and structural monitoring applications, with the aim of detecting quasi-static

displacements over long time periods.

The performance of the IBIS-L system depends on the type of configuration used and on

the operative measurement conditions (above all related to the reflectivity of the area

under investigation); however, the best performance characteristics can be defined as

follows:

For Ku band system:

 Maximum operational distance: 4000m;

 Image resolution in distance: 0.75m;

 Angular resolution: 4.3mrad;

 Accuracy in measuring displacements in the viewing direction: 0.1 mm (for

points with a good reflectivity - SNR>50dB – and depending on the impact of

atmospheric variation on the measure).

For X band system:

 Maximum operational distance: 4000m;

 Image resolution in distance: 1.5m;

 Angular resolution: 7.1mrad.

 Accuracy in measuring displacements in the viewing direction: 0.1 mm (for

points with a good reflectivity - SNR>50dB – and depending on the impact of

atmospheric variation on the measure).

The time required for instrument installation is about 2h.

The instrument has been specifically conceived for outdoor use and is equipped with an

installation system designed to guarantee high precision when repositioning it at a later

date. This is important to enable measurements to be performed over time without

needing to leave the instrument on-site.

The IBIS-L system offers the following advantages over currently available monitoring

systems (GPS, extensometers):

 Permits the operator to perform remote monitoring of the area (remote sensing),

without the need to access the area to install sensors or optical targets;

 Supplies a continuous displacement map of the entire area. The IBIS-L system

simultaneously measures all the displacements of the entire area illuminated by

the antenna beam, which can cover as much as hundreds of thousands of square

meters;

 Directly measure the displacements of the territory of interest in near real time;

 It can be used both day and night and in almost all weather conditions;

 It doesn’t require the continuous presence of an operator and can be controlled by

wireless connection.

This possibility of also performing long distance monitoring, with no need to install

sensors means that investigations can be performed even when:

 the area of interest is not accessible;

 the area of interest is particularly large and therefore would require many in situ

sensors;

In addition, when the monitoring activity is required to assure people’s safety in

emergency situations, the possibility of performing remote monitoring may be essential

for protecting lives.

Fig. 2.1 shows the composition of IBIS-L system. The main components are:

o Sensor module: this generates, transmits and receives the electromagnetic signal.

The sensor module is installed on the linear scanner: movement of the sensor on

the linear scanner permits the use of the SAR technique to obtain a two

dimensional image of the scenario. This module has a USB interface for

connection with the control PC and an interface to the positioning module;

o Linear Scanner, consisting of a 2.5 metre long aluminium track, along which a

slide is moved under the control of a step by step motor;

o The control PC, installed with the system management software. This is used to

configure the acquisition parameters, manage measurements and view the results

in real time;

o Power supply: this supplies power to the system through a battery unit or

connection to an external energy supply.

A detailed description of each component is reported in paragraph 3.

The sensor is fitted with two flanges, each with four filleted holes for the installation of

the pair of antennas (see par. 4.2).

3.3 Linear Scanner

The linear scanner (Fig. 3.15) consists of:

• A 2.5 m long track covered with aluminium sheeting;

• A trolley moved along the track by a step by step motor with a maximum

displacement of 2 m;

• An elevation pointing system to be installed on the trolley.

The elevation pointing system is the support for the IBIS sensor and permits the main

beam of the antenna to be orientated in elevation towards the area to be observed.

Fig. 3.15 – Installed linear scanner

Two mobile connectors link the sliding trolley to the sensor, while the panel at the back of

the linear scanner has the following interfaces:

• A five pin power supply connector;

• A B type USB connector;

to be connected to the power supply unit using the two cables which are part of the IBIS-

C KIT.

Fig. 3.16 – Back of linear scanner

Next to these connectors on the panel, there are three green LEDs which, when lighted,

indicate that the power supply is connected to the trolley positioning sensors, the step by

step motor and the IBIS sensor.

The linear scanner is used to move the sensor in along the track orthogonally to the

irradiating direction (antenna axis). The trolley is moved in steps for a total effective

length of 2 m. There is a waiting period between two successive steps equal to the

functioning time of the IBIS sensor.

For long-term monitoring the instrument must be positioned on a stable solid horizontal

base with minimum dimensions of 2000mm x 800mm x 200mm (length, width and

thickness), i.e. a concrete base. These measurements have been established to guarantee

the necessary robustness and permit the inclination of the linear scanner as required.

The system for fixing the linear scanner to the ground has been designed to allow it to be

accurately repositioned quickly and easily. In case of slow movements this means the

instrument can be used at intervals, over a period of several months, without having to

leave it positioned outdoors for the entire period. It is important to underline that the

expected movement between two discontinuous acquisitions has to be smaller than λ/4,

that is 4.3mm for Ku band system and 7.14mm for X band system, to not encounter in

displacement measurement ambiguity.

The basic fixture system consists of:

• Three support points (Fig. 3.17) positioned on three studs that fix the plane the

module will slide over.

• A reference sphere positioned under the track and inserted into a specific housing,

and which, when joined to the plane, forms an axis of rotation passing through the

centre of the sphere and normal to the plane.

• A positioning fork providing a buffer to block rotation with respect to the rotation

axis centred on the sphere.

• A screw opposite the buffer to block the module at the buffer point.

elements must remain installed at the measurement site since they are the basis of the

positioning reference.

For this reason, when the instrument is dismantled, we recommend you to protect the

anchoring elements with a wooden casing fixed to the base structure with plugs and

screws to avoid them being accidentally damaged or exposed to extreme weather

conditions.

A complete description of the installation procedure is given in par. 4.1

3.5 Power supply module

The power supply module supplies electric power to the system, in detail its function is to:

• Receive power from the mains electricity or from a generator set;

• Charge the pair of batteries required to guarantee continuous power supply even

in the case of a blackout;

• Distribute power and signal to the linear scanner and IBIS-L sensor.

It is a box with dimensions 560x600x840 mm, with two handles, two wheels for ease of

movement and three doors fitted with locks. Fig. 3.20 provides two views of the power

supply module.

Fig. 3.20 – Front (left) and back (right) view of the power supply module. Note the

handles, two wheels and three lockable doors

When the power supply unit is delivered, the handles are folded downwards to reduce

bulk and risk of damage during transportation. To reposition the handles proceed as

follows for both handles (following the procedure shown in sequence in Fig. 3.22):

1. completely unscrew the top screw on the handle blocking mechanism and loosen

the lower screw;

2. rotate the handle anticlockwise until it is positioned upright;

3. reinsert and screw in the previously removed screw

NOTE

: The instrument observation direction is perpendicular to the template axis; the correct

observation direction is when standing looking at the template, you have two

regulation screws to your left and a single screw to your right (see Fig.4.2).

Fig. 4.8 – View of the template placed on the base

4.1.2 Preparing the anchor points for the linear scanner

This section describes the sequence of operations to be performed to set up the linear

scanner anchoring elements

1. position the three template height regulating screws as low as possible (see Fig. 4.8 );

2. mount the optical view finder on the template;

3. place the template on the base;

4. use the optical telescope to point at the scenario to be monitored, orientating the template

on the base surface. When choosing the area to be monitored, take the width of the

antenna beam into consideration (see par. 3.2);

5. use the spirit level to make sure the template is perfectly horizontal by turning the handles

of the three threaded screws, making sure you do not raise the template too far from the

surface of the base;

6. mark the position of the 5 large holes (∅16 mm) present on the template onto the base;

7. remove the template and drill 18 mm holes for the studs to a depth of about 11 cm,

carefully clean the holes with compressed air. Be careful to keep the drill vertical to avoid

the need to widen the holes later;

8. mount the spacer, screwing it to the two smallest holes present on the central plate of the

template (Fig. 4.9);

9. mount the three long studs, inserting them into the three holes at the ends of the template

with the nut and lock nut and insert the washers (Fig. 4.9), controlling that the stud

protrudes from the upper nut by about at approximately 4cm;

10. mount the two shorter studs on the spacer with the nut, lock nut and M16 washer (Fig.

4.9) so they protrude from below the template the same distance as the other three studs

(all 5 studs must touch the ground at the same time);

11. minimising the protrudance of the three regulating screws, replace the template with these

studs onto the base, inserting the studs into the previously drilled holes and ensuring that

all the studs enter easily into the holes without any obstacles;

12. move the studs fixed to the template in and out of the holes on the base several times to

ensure that they enter well to the correct depth (widen the diameter of the holes if

necessary);

13. use the template regulating screws to fix the height position of the studs so that they

penetrate about 7-8 cm inside the respective holes;

14. place the template in the exact position and level it using the three regulating screws;

15. remove the template from the base, keeping all the studs and screws attached to it;

16. inject enough resin into each hole to block the studs (Fig. 4.10 );

17. insert the studs, still attached to the template, into the holes making sure that the position

coincides with that previously measured;

18. wait for the resin to dry completely (for the time required, read the instructions on the

tube), then remove the 5 nuts and the M16 washers that keep the studs fixed to the

template and lift off the template (the base should now be left with the five studs with 5

nuts and 5 M16 washers).

4.1.3 Mounting the linear scanner

The following sequence of operations describes the installation of the linear scanner onto

the anchoring elements:

1. mount the two base washers on the two closely positioned studs (Fig. 4.11);

Fig. 4.11 – Mounting the base washers

2. fix the positioning fork on the other stud on the opposite side of the base, positioning it

with the axis of the two screws perpendicular to the direction of the axis of the template;

3. screw the third base washer above the positioning fork (Fig. 4.12);

NOTE

: the resin is malleable for about 5 minutes before setting at summer temperatures, so the

time between the moment of the first injection to the insertion of the studs into the resin

filled holes must be less than this to avoid the need to drill new holes.

4. mount the concave part (black color) of the three spherical thrust bearings onto the three

washers and lubricate them with the water-repellent silicon oil;

5. mount the convex part (white colour) of the three spherical thrust bearings (Fig. 4.13);

Fig. 4.13 – Sequence for mounting the spherical thrust bearings

6. insert the plate with the spherical housing onto the two short central studs, sitting it on the

washers and the two nuts already screwed onto the stud;

7. grease the spherical housing with silicon waterproof grease;

8. place the track on the three spherical thrust bearings, making sure that the sphere is

properly positioned in its housing;

9. level and position the track by regulating the base washers and the spherical housing

plate;

10. regulate the height of the spherical housing plate so that the sphere is positioned in its

housing a little further than its maximum circumference (Fig. 4.15) but without touching

the bottom;

11. check the spherical housing is level, it is easier to perform this operation after removing

the linear scanner;

12. tighten the spherical housing plate tighten the nuts against the base washers, making sure

that the three washers do not rotate thus loosing the position obtained previously , and that

the fork is in the correct position, perpendicular to the axis of the track.

position, centre shows the sphere position too high, right shows the sphere touching the

bottom of the housing

13. reposition the linear scanner on the three studs;

14. block the positioning fork M10 buffer screw with the lock nut and M10 washer, taking

care that the stud remains in the centre of the flange hole to permit the track to

elongate/contract due to thermal excursions. Use a marker pen (or a little resin or wax) to

mark the position of the nut with respect to the positioning fork so as to have a reference

for repositioning the linear scanner, since the nut cannot be moved after it has been fixed;

NOTE

: be especially careful when mounting the positioning sphere, which is fundamental when

repositioning the instrument. The spherical housing is countersunk to make the insertion of

the sphere easier, so the maximum circumference of the sphere should pass this

countersinking without touching the bottom of the spherical housing, to ensure the

reference is high precision. Regulate the height of the spherical housing plate until this is

achieved.

15. hand tighten the M8 anti veering screw and lock it with an M8 washer and lock nut so that

it keeps the linear scanner flange fixed, without there being any play between the two

screws, but keeping it free to slide for any elongation/contraction due to thermal

excursions undergone while the instrument is positioned at the measurement site;

16. place the three remaining spherical thrust bearings, convex side uppermost, onto the three

external studs (the ones that have the track supports inserted), lubricate them with the

water repellent silicon grease and position the concave parts of each one on top of them

(Fig. 4.16);

17. now insert two disc springs and an M16 washer on each of these studs (Fig. 4.16);

18. screw on the M16 fixing nuts to these three studs and hand tighten them, being careful not

to tighten them too much (the disc springs must remain a little open) (Fig. 4.16).

Fig. 4.16 – Steps 16 to 18

The suspension function provided by the spherical thrust bearings maintains the support

horizontal and compensates for any deviation of the position of the studs from the axis

with respect to the horizontal plane of the track, while the springs keep the track fixed to

the supports while permitting it to undergo normal expansion.

When the linear scanner is reinstalled onto an existing installation site, the operations to

be performed are those described in points 4, 5, 8 and then from points 15 to 18 of this

paragraph. The module to be repositioned must simply be placed on the spherical thrust

bearings and then fixed with the M16 nuts and the M8 screw, without touching the

position of the base washers.

4.2 Installation of the IBIS sensor and module connection

After having installed linear scanner, the IBIS sensor can be installed on the trolley. To do

this, the following operations must be performed in sequence:

1. loosen the two knobs on the trolley dovetail guides sufficiently to permit the

insertion of the elevation pointing system (the sequence of points 1 to 3 is shown

in Fig. 4.17);

2. keeping the pointing system tilted downwards, align the two front pairs of

dovetail guides then rotate the elevation pointing system resting it on the trolley

(loosen further the knobs if it does not completely rest on the trolley);

3. tighten the two knobs;

following list describes the operations requires to start up and use IBIS-L:

1. if necessary, connect the power supply module to an external power supply

using the cable supplied in the upper area of the power supply module and

switch on the switch that controls input from mains (external AC input). This

mode avoids using the charged batteries.

2. start up the control ad acquisition PC;

3. switch on the three switches on the power supply module that control :

a. the sensor (sensor power supply);

b. linear scanner (linear scanner power supply );

c. pc power supply (Lap Top PC );

4. connect the USB connector in the upper area of the power supply module to

the PC (it is always best to connect it after having switched on all the

equipment to avoid any possible recognition problems of the USB device by

the operative system);

5. start the IBIS-L Controller v. 02.00.002 program clicking on the desktop icon;

6. USEFUL TIPS

6.1 Installation

The successful outcome of a measurement campaign starts from the initial inspection

survey: the first main aim of the inspection survey is to establish the exact position of the

base that the linear scanner will be installed onto.

The characteristics of a good position are to:

• be in the direction of the displacement to be measured;

• have sufficient space to operate safely and to have room for the linear

scanner, the power supply module and the operators;

• be easily accessible for the transportation of material (remember that the

packing case weighs 107 kg and is bulky to move);

• have an external power supply. If this is impossible, a power generator must

be supplied;

During the inspection survey, it is also useful to perform a GPS measurement of the

position the instrument will have, and of the area to be monitored, obtain maps, including

3D maps or DEM of the area and ensure that all necessary permits have been obtained for

the construction of the base and monitoring the area of interest. It is always a

recommended to inform the competent authorities.

It is recommended to check sufficiently in advance that the contents of the case have been

properly loaded to avoid any damage during transportation, ensure that the power supply

module batteries have been fully charged (see par 3.5) and arrange a suitable means of

transport capable of containing all the necessary material. A list of this material is given in

paragraph 4.1.

Remember that subsequent installations after the first one require a new set of anchoring

elements for the linear scanner.

Installation requires the work of at least two or three people and at least one must be

capable of using a percussion drill.

The recommended size for the base is 2000mm x 800mm x 200mm; in reality, this is the

minimum size that provides sufficient space to correctly orientate the linear scanner and to

provide a sufficiently robust concrete base. For ease of installation and use, the base

should have a height of about 600 - 700 mm.

The orientation of the linear scanner should be chosen considering the scenario to be

measured and the width of the antenna beam, to make sure that the entire scenario falls

inside the instrument’s field of vision.

NOT

: the IBIS-L system does not include an electrical energy generating system. In fact the

power supply unit can only store energy in its batteries and is not fitted with a 220 V

output, (for a percussion drill for example). The choice of power supply system is left

to the user, who will have to consider the energy absorbed by the instruments to be

used.

IDS Ingegneria Dei Sistemi S.p.A. N°doc: MN/2009/070 - Rev. 1.1

IBIS-L v.02.00 - User manual

60 / 65

6.2 Use

When you want to download data directly from the PC onto an external USB HD, the

control program has to be paused (we recommend you pause the system when the trolley

is positioned in the centre of the track, waiting to perform a new acquisition), then

download the data and restart the acquisition. If you have to disconnect the USB

connector from the apparatus, the program will signal a missing device error and you will

have to shut down and restart the software.

When the apparatus is functioning, ensure that nobody can pass or stand in front of the

IBIS sensor to avoid ruining the acquisition. Also make sure that there is no vegetation

high enough to block the electromagnetic waves.

6.3 Dismantling

When dismantling the measurement site, carefully check exactly what is to be removed

and accurately place the pieces to be stored in the packing cases.

In addition, make sure the elements that remain on the site for a subsequent measurement

campaign are sufficiently protected. For this reason, we recommend you cover the

elements with a wooden box, to be fixed to the base using plugs and screws, and that you

lubricate the spherical housing well with water repellent silicon grease.

7. MAINTENANCE

Maintenance of the module can be divided into three sections:

• Maintenance of the module base;

• Maintenance of the movement system;

• General maintenance of the module.

7.1 Maintenance of the module base

While the apparatus is functioning, the spherical thrust bearings must be kept clean and

lubricated with water repellent silicon grease. Depending on the environmental conditions

(dust, water, material deposited by the wind, etc.) these parts must be dismantled, cleaned

and lubricated every two months. Each time the module has to be installed, the spherical

housing and the sphere must be cleaned and lubricated with water-repellent silicon grease.

7.2 Maintenance of the movement system

The motor, the speed reducer and all moving parts apart from the trolley wheels do not

require maintenance since they have been designed to have life long lubrication. Even

though the trolley wheels and the tracks are protected by a cover, they may become dirty

due to material deposited by atmospheric agents. For this reason, they should be cleaned

and lubricated with water-repellent silicon oil at least once every two months and any

time deposits are found (due to unforeseeable events, which may occur after many months

or even after a few weeks, therefore we recommend you control the state of the

instrument as often as possible).

7.3 General maintenance of the module

General maintenance of the module is foreseen after every two years of operation. We

recommend this should be performed by specialised personnel at the constructor’s site

Time between maintenance check ups Maintenance action

2 months Clean and lubricate the spherical thrust

bearings;

Clean and lubricate the trolley wheels and

track.

2 years General maintenance performed by

specialised personnel authorised by IDS.

Appendix B - ELEMENTS OF RADAR TECHNOLOGY

B.1 Antenna beam

The term antenna main lobe (or beam) is intended as the angular area within which the

antenna concentrates most of the power it is supplied with.

The main lobe of an antenna can be schematically represented as a truncated cone with an

elliptic base, where the cone vertex is positioned in correspondence with the antenna. The

base of the cone is elliptical since antennas typically have lobes with different angular

amplitudes in the elevation (V) and azimuth (H) planes.

Fig. B. 1 – Schematic diagram of the antenna beam

The following parameters are normally defined to quantify the antenna beam amplitude:

• The beam at -3dB: angular area within which antenna gain is more than 50% of the

maximum gain (-3 dB = 10*log10(0,5)).

• The beam at -10 by: angular area within which gain is more than 10% of the

maximum gain (-10 dB = 10* log10(0,1)).

From an applicative point of view, this means that the sensor must be pointed so that the

scenario of interest falls inside the antenna beam, preferably at -3dB. Therefore the

distance at which the instrument should be positioned and its inclination should be chosen

as a function of the antenna beam being used.
