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.

BE CAREFUL
The Antenn a Box may on ly be moved in on e d irection. It may
only be pulled or pushed in the direction of increasing scanning
coordinates .
• Scan Offset (m): each radar scan is characterised by an
in it ial L and/or T co-ordinate Therefore, once you have
inserted the starting point co-ordinate for the investigation
(“coord. value”) as a function of the type of scan, the
other reference co-ordinate must be defined in the “Scan
Offset (m)” field. The follow ing option must then be
selected:
• On L/T coordinate ” selection
Here, you have to manually measure the value of
the co-ordinate corresponding to the centerpoint of
the antenna box w ith respect to the reference
system selected previously, and insert it into the
active field.
For example, if you h ave to perform a transversal
scan starting from the co-ordinate T=2 and L=2,
you must set the type of scan to Transversal and
then set the actual value of the T co-ordinate (e.g. 2
m) in the “Coordinate (m) ” field. Next, activate the
“L coordinate” in the “Scan Offset (m)” area,
setting it to 2 in th is case. The scan can now be
performed.

7. HOW TO USE THE DETECTOR
The main targets w hen performing ut ilities invest igat ions w ith the
DetectorDuo consist of either extended structures (such as an interface
betw een layers, pipes parallel to the invest igat ion d irection etc.) or
quite small structures (such as pipes perpendicular to the invest igat ion
direction, cavities and rocks etc.).
Fig. 7.1 show s how a flat interface g ives rise to a f lat trace w hile a
small structure such as a pipe produces a hyperbolic trace. This is
because the echoes form the flat plane at d ifferent values of x take the
same time to reach the DetectorDuo. For the pipe, how ever, 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 med ium increases ( vm ), the ratio
betw een the flight t ime of the outw ards and return signal twt
relat ive to echoes originat ing from lateral points and the twt
relat ing to the top surface of the target decreases. Therefore the
hyperbola w idens w ith higher propagation speed, vm .
o With increasing depth of the target, the ration betw een the twt
relat ing to the echoes from the side points and the twt relating to
the top surface of the target decreases. Again, the hyperbola
w idens w ith increasing target depth.
o For equal propagation speed, depth and type of target, the
hyperbola w ill be w ider for geometrically larger targets (for
examples for w ider diameter pipes).
When int erpreting the maps, it is therefore a good idea to remember
that the w idth of a hyperbo la does not just depend on the geometrical
size and shape of the target. Fig. 7.2 show s tw o maps featuring echoes
of an irregular interface betw een tw o layers w ith different dielectric
properties (asphalt) and six pipes situated perpendicular ly to the
direction of investigat ion.

As can be seen in Fig. 7.2, the echo of a target do esn’t simple consist
of a single dark band, it consists of alternate dark and light bands.
These derive from the signal min imums and maximums reflected back
from the target (in fact, the black and w hite bands represented in the
figure correspond to maximum and min imum sign al amp litude
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 ordin ates is compared w ith a family of
hyperbolas traced w ith ordinates in meters, obtained from that in ns
ordinates w ith various values of v m. The best vm approximation to the
real v alu e is that w ith the most similar aperture to that of the on e
traced in time ordinate. Once v m has been identif ied, the depth of the
target corresponding to the hyperbolic section can be found. There are
no defin it ive criteria for interpreting d iagrams 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 investigat ion, and
use it to help choose the most appropriate equipment and invest igat ion
parameters. To conclude, w e have an example below of a real situation
featuring tw o pipes side by s ide (Fig. 7.3). This example is sign ificant
in that it show s the diagrams of the same structure (the pipe) placed
perpendicular ly then parallel to the direction of investigation.

APPENDIX A - THE PRELIMINARY INVEST IGAT ION
The first fundamental phase for any field survey consists in the
prelimin ary inv estigat ion : its scope is to acquire all the necessary
information for the log istics of the operation, taking into account the
objectives to be performed.
In the specific case of a georadar invest igat ion for underground
utilities searching, the first thing to consider is the accessibility of the
site, in terms of taking into account the space availab le for the passage
of the antenna trolley and considering any architectural obstacles that
could cause an obstacle to the data acquisit ion phase. Often, in fact,
the invest igat ion is performed in streets, squares and on pavements
w ith a relativ ely high level of urban traffic, and above all, in the
presence of randomly parked cars.
The main po ints 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 d ifficult ies in accessing the site must be considered;
 The space availab le;
 The presence of parked cars;
 The level of traffic;.
It is the task of the user to take these points into consideration w hen
programming the w ork.
APPENDIX B - THE TECHNICAL MAPS
Technical maps of the existing utilit ies are produced by the various
utilities companies.
These give g eneral ind ications in a schematic w ay about the type and
position of the ut ilities that are managed and/or have been constructed
by them.
These maps can be requested by fax ing or w rit ing to the cartographic
or plann ing office of the companies, specifying clear ly the streets and
areas of interest.

DETECTOR DUO SYSTEM – User manual
N doc: MN/2009/028 - Rev. 1.1
The most important types of utilities (w hich may be managed by
different agencies) to be considered are:
 Public Street Light ing
 Low , Medium and High Vo ltage Electricity Cab les
 Water supply
 Gas
 Telephone Cab les
 Sew ers
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 exhaust ive one, of the
utilities that are present.
For this reason, it is important that the user activat es the procedures
for obtaining these maps w ell in advance to make sure that they w ill
be availab le during the data extraction phase.
APPENDIX C - OPENING MANHOLES
This phase is normally performed once the acquisit ion phase has been
