1. INTRODUCTION
The Detector Duo is an innovative system capable of detecting tubes
and both metallic and non metallic cables buried underground.
Following standard radar principles, the Detector Duo uses a high
performance electromagnetic sensor equipped with e.m. transmitters
and receivers.
The fundamental characteristic of this system is the simultaneous use
of two frequencies, permitting the identification of both shallow and
deep utilities at the same time.
The groundbreaking control unit is extremely compact and lightweight
at just 1Kg , and is compatible with 2 ATS antennas with frequencies
of 700MHz and 250MHz located in a single container. The simplicity
of this instrument means that a brief training course is sufficient to
permit it to be used correctly.

3.1.3.1 Charge level and battery replacement
When the spy light is lit next to the power supply port on the radar,
this indicates that the system is powered: if it is not lit, this means that
either the cable is not connected correctly or that the battery is flat
(less than 10V). The battery has an autonomy of around 12 hours.
When the battery runs, down the instrument must be switched off,
another battery connected, and the system can be started up again. A
flat battery can be completely recharged in around 3 hours with the
appropriate battery charger (see Fig. 3.9 right). A software message on
the PC informs the user of the battery charge level with a BATT
button (see Fig. 3.9 left), which changes color as follows:
Green if the battery is fully charged,
Yellow if it is semi-charged,
Red if the battery is flat.

storage. Store batteries in a cool, dry place. Do not leave
batteries in direct sunlight during the summer months or
any other unusually hot location. Do not expose battery
terminals to metal objects or moisture, which may short-
circuit your battery. For long-term storage, store batteries
below 50% state of charge because the deterioration of
battery capacity is slower at lower state of charge.
However, do not store batteries in a fully discharged
state.

acquisition (generated by a buried pipe or cable), go back,
moving the trolley in the opposite direction to the acquisition
direction. This temporarily suspends acquisition and produces a
vertical line on the data screen (see Fig. 5.17).

In particular, during the acquisition phase, both the radar maps can be
viewed (Fig. 5.20) when the DUAL 250-700 antenna is operated. In
fact, initially, the software automatically displays the
Shallow
radar
section (700MHz); to view both the sections together , click once with
the left mouse button in the bottom right section named Deep to
make the radar section for the 700MHz appear together with the
250MHz antenna. The two sections are separated by a yellow
horizontal line.
Then by clicking twice with the left mouse button on the horizontal
yellow line and dragging upwards or downwards, the two maps can be
viewed in more or less detail. In addition, if the Shallowand Deep
labels in the top left of the sections hide a target, they can be moved to
the bottom right of the radar maps simply by clicking twice with the
left mouse button on the yellow “Shallow or “Deep labels.

you must set the type of scan to Transversal and
then set the actual value of the T co-ordinate (e.g. 2

7. HOW TO USE THE DETECTOR
The main targets when performing utilities investigations with the
DetectorDuo consist of either extended structures (such as an interface
between layers, pipes parallel to the investigation direction etc.) or
quite small structures (such as pipes perpendicular to the investigation
direction, cavities and rocks etc.).
Fig. 7.1 shows how a flat interface gives rise to a flat trace while a
small structure such as a pipe produces a hyperbolic trace. This is
because the echoes form the flat plane at different values of
x
take the
same time to reach the DetectorDuo. For the pipe, however, the echoes
from its sides take a longer time to reach the DetectorDuo than the
echoes from its top surface.

o
As the propagation speed in the medium increases (
v
m
), the ratio
between the flight time of the outwards and return signal
twt
relative to echoes originating from lateral points and the
twt
relating to the top surface of the target decreases. Therefore the
hyperbola widens with higher propagation speed,
v
m
.
o
With increasing depth of the target, the ration between the
twt
relating to the echoes from the side points and the
twt
relating to
the top surface of the target decreases. Again, the hyperbola
widens with increasing target depth.
o
For equal propagation speed, depth and type of target, the
hyperbola will be wider for geometrically larger targets (for
examples for wider diameter pipes).
When interpreting the maps, it is therefore a good idea to remember
that the width of a hyperbola does not just depend on the geometrical
size and shape of the target. Fig. 7.2 shows two maps featuring echoes
of an irregular interface between two layers with different dielectric
properties (asphalt) and six pipes situated perpendicularly to the
direction of investigation.

As can be seen in Fig. 7.2, the echo of a target doesnt simple consist
of a single dark band, it consists of alternate dark and light bands.
These derive from the signal minimums and maximums reflected back
from the target (in fact, the black and white bands represented in the
figure correspond to maximum and minimum signal amplitude
respectively). A hyperbolic echo can be used to convert the ordinate of
the map from time (nanoseconds = ns) to depth (meters= m). To do
this, the hyperbola traced in ns ordinates is compared with a family of
hyperbolas traced with ordinates in meters, obtained from that in ns
ordinates with various values of
v
m
. The best
v
m
approximation to the
real value is that with the most similar aperture to that of the one
traced in time ordinate. Once
v
m
has been identified, the depth of the
target corresponding to the hyperbolic section can be found. There are
no definitive criteria for interpreting diagrams and often you have to
depend on experience. In any case, it is best to collect the largest
possible amount of information for an area under investigation, and
use it to help choose the most appropriate equipment and investigation
parameters. To conclude, we have an example below of a real situation
featuring two pipes side by side (Fig. 7.3). This example is significant
in that it shows the diagrams of the same structure (the pipe) placed
perpendicularly then parallel to the direction of investigation.

APPENDIX A - THE PRELIMINARY INVESTIGATION
The first fundamental phase for any field survey consists in the
preliminary investigation: its scope is to acquire all the necessary
information for the logistics of the operation, taking into account the
objectives to be performed.
In the specific case of a georadar investigation for underground
utilities searching, the first thing to consider is the accessibility of the
site, in terms of taking into account the space available for the passage
of the antenna trolley and considering any architectural obstacles that
could cause an obstacle to the data acquisition phase. Often, in fact,
the investigation is performed in streets, squares and on pavements
with a relatively high level of urban traffic, and above all, in the
presence of randomly parked cars.
The main points to be considered during this phase are described
below:
Specific permissions must be obtained (access to pedestrian
zones, permission to interrupt the traffic flow, etc.);
Any difficulties in accessing the site must be considered;
The space available;
The presence of parked cars;
The level of traffic;.
It is the task of the user to take these points into consideration when
programming the work.
APPENDIX B - THE TECHNICAL MAPS
Technical maps of the existing utilities are produced by the various
utilities companies.
These give general indications in a schematic way about the type and
position of the utilities that are managed and/or have been constructed
by them.
These maps can be requested by faxing or writing to the cartographic
or planning office of the companies, specifying clearly the streets and
areas of interest.

The most important types of utilities (which may be managed by
different agencies) to be considered are:
Public Street Lighting
Low, Medium and High Voltage Electricity Cables
Water supply
Gas
Telephone Cables
Sewers
Even though they may be very generic, these maps represent an
important support during the extraction and data interpretation phases,
since they give the user a first idea, if not an exhaustive one, of the
utilities that are present.
For this reason, it is important that the user activates the procedures
for obtaining these maps well in advance to make sure that they will
be available during the data extraction phase.
APPENDIX C - OPENING MANHOLES
This phase is normally performed once the acquisition phase has been
completed, and consists in opening the manholes present in the
investigated site.
The data regarding the depth, diameter, and direction of the utility
should be saved on the work sheet: this will provide you with further
reference data during the interpretation phase, and will allow
propagation velocity estimates to be performed in order to calculate
the depth of the identified utility as precisely as possible.
