INTRODUCTION This document provides an introduction to the IBIS-S system (Image By Interferometric Survey-S), with particular reference to the concepts the user must learn before starting to use this device. Therefore we recommend that you read the entire document before starting the system. If technical assistance is required, please use the contact numbers provided on page 3 of this manual. 1.1 Scope This document will provide the operator with all the necessary knowledge to install and maintain the IBIS-L system. In particular, the manual describes: - The contents of the cases; - The procedure for installing and dismantling the system; - Information for the safe use of the system. 1.2 Field of application This document applies to the installation and dismantling of the of the IBIS system in S configuration and its use in the field for monitoring quasi static or dynamic phenomena. 1.3 Authorisation for use – national restriction European countries IBIS-S system has been classified by 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-S has so been included in the ERC/REC 70-03 which defines the SRD equipment. For Ku band system While the European countries update their national frequency allocation table applying the new recommendations, currently the use of IBIS-S system outside a laboratory can still be subject to authorisation by the Competent Ministry of the country where the system will be used. Please refer to the country’s Competent Ministry to know whether there is the need of an authorisation. 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 will be used to know if there are limitations in the use of X band IBIS-S equipment.

OVERVIEW 2.1 How to use this manual This manual consists of the following chapters: • Chapter 3 - contents of the cases • Chapter 4 - IBIS-S system hardware configuration • Chapter 5 - IBIS-S system installation and dismantling procedure • Chapter 6 - Useful Tips • Appendix A - Restrictions • Appendix B - Technical Specifications • Appendix C - Elements of Radar Technology 2.2 General description of the IBIS-S system The IBIS-S system is designed to remotely measure displacements with a sampling frequency up to 200 Hz with an accuracy as fine as a hundredth of a millimetre. The performance of the IBIS-S system depends on the type of configuration used and on the operative measurement conditions; however, the best performance characteristics can be defined as follows: • Maximum operational distance: 1000 m; • Maximum image resolution in distance: 75 cm; • Accuracy in measuring displacements in the viewing direction: 0.01 mm; The time required for instrument installation is about 20 minutes, and the same time is required for its dismantling. The instrument has been specifically designed for outdoor use and is equipped with IP65 level protection and is supplied with a notebook PC specifically designed for outdoor use in extreme conditions. The IBIS-S system offers the following advantages over currently available monitoring systems (GPS, extensometers, accelerometers ): • remote monitoring without the need to access the structure to be monitored • Resolution of 0.75 m which permits IBIS-S to identify a large number of “virtual displacement sensors” on the area under investigation, simply by remotely targeting the scenario; • Acquisition frequency of the entire measurement area up to 200Hz; • Directly measure the displacements in real time: IBIS-S can process acquired data and display the displacement of a point selected from the scenario in real time. This IBIS-S characteristic permits the monitoring of damaged structures with real time generation of alarm signals in case of collapse danger;

All rights reserved. • Displacement measurement accuracy up to 1/100 of a millimetre: the interferometer technique permits IBIS-S to measure movements with a high degree of accuracy and precision, never seen before in a remote monitoring system; • Quick to install; • Functioning conditions suitable for long term monitoring :  Automatic functioning (presence of an operator not necessary while functioning);  Can operate night and day;  Can operate in any weather conditions; The IBIS-S system is particularly suitable for all applications where it is important to measure displacements of a structure without the need to have direct access to it , or when short investigations must be performed quickly. By performing long range measurements, without the need for direct contact with the structure to be monitored, IBIS-S permits measurements to be performed even when: • The area of interest is not accessible; • The structure is very tall such as a large antenna or a tower; • The structure is covered by paintings or sculptures and it is not feasible to perform contact monitoring. In addition, in emergency situations when monitoring activities are required to guarantee safety, the possibility if performing remote monitoring may be an essential condition towards saving lives.

All rights reserved. 5.2 IBIS-S installation In order to simplify system installation, the area where the IBIS-S is to be installed must be chosen carefully. The selected area must satisfy the following requirements: • The scenario of interest must be visible and the view must be uninterrupted by the presence of obstacles from the chosen point (trees, fences, buildings); • The area must be sufficiently large to mount the tripod, manoeuvre with the case and for the operator to work from (the tripod covers at most a circular surface 1.5 m in diameter while the case has a base of 85x55 cm); • The surface must be compact and stable to avoid any subsidence under the weight of the instrument. Once the optimal installation point has been chosen, proceed as follows: 1. Remove the tripod form its bag. 2. Open the tripod and fix it at the desired height using the levers and blocking screws. 3. Ensure that all the joints have been firmly tightened to optimise the rigidity and stability of the tripod. 4. Position the tripod on the ground being careful that the area chosen is stable. 5. Level the tripod using its spirit level, adjusting the length of the individual legs if required . Fig. 5.4 – Installed tripod 6. Remove the triaxial head and handles from the case.

USEFUL TIPS 6.1 Installation The successful performance of a field measurement campaign starts with the initial inspection survey. The scope of this survey is the evaluation of the following aspects: • Identification of a suitable installation point for the IBIS-S in terms of scenario visibility and stability of the point the equipment will sit on. The characteristics of a good position can be summarised as: o direction of the displacement to be measured coincides with the ideal line traced between the sensor and the measurement point; o there being sufficient space to operate safely and to position the tripod, the IBIS-S case and for the operators to move around; o easily accessible to permit all the required material to be brought to the site. • An evaluation beforehand of the quantity, quality and position of reflecting points present in the scenario; • The possibility to install artificial reflectors if those present in the scenario are not sufficient. Installation of artificial reflectors eliminates one of the advantages of IBIS-S, because it means that there must be access to the site. However, the use of artificial reflectors allows a better accuracy in displacement measurement and identification of the point the displacement is measured for. • The presence of possible disturbances due to vegetation, foliage or other sources, near to the intended displacement measurement points. • The number of measurement points and their location in the scenario. The IBIS-S sensor measures displacements along the ideal line joining the sensor to the point being examined (radial displacement), therefore if the real displacement occurs in another direction, the detected displacement must be projected on the basis of geometrical considerations (Fig. 6.1). Fig. 6.1 – Projection of displacement data Real displacement Measured displacement

To avoid making projection errors of the displacement data and when possible, we recommend positioning the sensor so that the displacement direction of the interested object occurs along the line that joins the point to the sensor. If this is not possible, in order to minimise projection errors, an accurate georeferencing of the sensor must be performed with respect to the scenario/structure of interest.. Maps of the scenario and /or drawings of the buildings to be observed (in 3D if possible) should be obtained. If the monitoring concerns a public building or infrastructure , make sure that all required authorisations have been obtained. It is always a good idea however to warn the responsible local authority before starting to perform measurements. When extending the tripod to reach the desired height, the following basic precautions should be taken to optimise the rigidity of the structure: • Adjust the height of the structure by first lengthening the middle section of the legs, then the thinner bottom sections; • If possible, avoid extending the central column; • Avoid opening the legs wide when they have been significantly extended in length. Fig. 6.2 – Tripod 6.2 Use When the equipment is functioning, it is a good idea to ensure that nobody can pass or stop in front of the radar sensor to avoid a reduction in the quality of the radar acquisition. When performing a field measurement campaign , it is very useful to have a folding table where the control and acquisition PC can be positioned.

APPENDIX C - ELEMENTS OF RADAR TECHNOLOGY C.1 - Definitions C.1.1 Main antenna lobe 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. C. 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 depending on the antenna beam being used. V plane H plane
