Fig. 2-19 –Antenna for the SRS-FW400 system (red arrows show dragging direction)
The system includes from 1 to a maximum of 4 antennas and all antennas have a
frequency of 400MHz.
Each antenna is marked with a different colour on the case to simplify antenna
connection. So when connecting each antenna, make sure the corresponding coloured
cable is connected to the control unit on ports ANT. 1, ANT. 2, ANT. 3, ANT. 4,
depending on the number of antennas to be used (see an antenna in Fig. 2-18).
Each antenna must be mounted with the red arrows parallel to the drag direction (or
parallel to the tracks).
The dedicated “H” plate can be fixed to the top of the case so the case can be mounted
onto any customized mechanical kit.
2.7 Mechanical kit
IDS provides to offer a special mechanical kit, in order to mount in a correct and efficient
way the antennas in front of the locomotive.
In details IDS provides:
• 6 supports in stainless steel with “L” shape

here you can set the acquisition mode of the system, which
can be either
o Wheel driven
field selected, in this mode, the radar acquisition is
set using the position sensor.
o
If the wheel is not used, y ou can set the radar acquisition to be
performed under a constant time regime; the value inserted in the
Auto
Stacking
field indicates the number of sweeps averaged
during the acquisition phase.
o
The User Stacking function on the other hand allows you to control
the number of sweeps averaged. The acquisition is still controlled
in this configuration by the p osition sensor (wheel, hip-chain
encoder or manual trigger). Once the signal from the position
sensor has been received, the system performs an average of the
number of sweep s selected by the user and emits an acoustic signal
to confirm that the data has been saved.

iii.
Marker 1 step:
this field rep resents the distance between two
reference lines marked on the site. The default value is 10 m. This
function allows you to realign the radar sections to compensate for
any distance variations with respect to the data acquired with the
position sensor wheel. This realignment is performed according to
the value set in the
Marker 1 step box
. This setting is typically
used for realigning longitudinal scans. If you set the marker with a
sp ecific p osition and then p ress the button shown in Fig. 4-29,
contained in the window shown in Fig. 4-31 at a distance of
±
20%
either before or after this assigned point, the
Pos. Marker
will be
transformed into a
User Marker
when the file is saved (see Fig.
4-31 and point 3 of Par. 4.6).
Fig. 4-29 – Pos. marker button
iv.
Longitudinal/Transversal – Inverse direction:
this field allows
you to select the scanning direction of the radar section about to be
acquired. When filling in this field, remember that
Longitudinal
(
L
)
means the scans is performed parallel to the zero referen ce line (T
axis), while a scan perpendicular to this line is called a
Transversal
scan
(
T
) (see Appendix A). The
Inverse direction
field allows you
to perform a T/L scan in the opposite direction, i.e., moving in a

decreasing coordinate direction. In any case, you must return back
to the same starting axis used for the forward scan.
v.
Coordinate (m)
: This field allows you to insert the values of the
set T or L co-ordinate. R emember to indicate if a coordinate is
negative. Check the current T or L coordinate on the site and insert
it into the relative field. Remember that, desp ite the actual
dimensions of the antenna trolley, it is represented in the Cartesian
reference system by a single point that corresponds to its
centerpoint. The position of this point varies depending on the
array configuration that has been set. When moving the antenna
trolley, make sure the centerpoint is on the scan line, at the defined
coordinate.
Coord. value
: insert the value of the coordinate to be
maintained constant during the scan in this field.
Coord. Step
: this field contains the step value that is added
automatically to the current value when a scan is finished ,
leaving the system ready to start the next scan. The preset value
= 2 m between scans. For example, if a longitudinal scan has
been chosen and it starts from a point with coordinates
T, L

vi.
Scan Offset (m)
: each radar scan is characterised by an initial L
and/or T co-ordinate Therefore, once you have inserted the starting
point co-ordinate for the investigation (“
coord. value
” in Fig. 6-9)
as a function of the type of scan, the other reference co-ordinate
must be defined in the “
Scan Offset (m)
” field. There are two
alternatives for this operation:
Select “
With 1st Marker 1 step
”: this selection automates
the insertion of the second L or T co-ordinate when the
antenna array crosses the zero line starting from a negative
co-ordinate. This procedure is normally used when there are
many irregularities on the site such as parked cars, indents

in the pavement, etc. In these cases, it can be very time
consuming to calculate the distances each time as described
above and is more convenient to select the
With 1st
Marker 1
box after having just set the initial L or T co-
ordinate.
The system automatically reco gnises the path performed in
the negative portion and automatically associates the
negative starting co-ordinate to the last L or T co-ordinate.
For example, for the case of the Transversal scans shown in
Fig. 4-30, first we select the scan type (in this case
Transversal) in the “
Scan Settings
” window (Fig. 4-28).
Then we set the current value of the T co-ordinate (2m in
this case) in the “
Coordinate (m)
” field; finally, we activate
the “
With 1
st
Marker”
option in the “
Scan Offset (m)
” field.
In this way, the acquisition starts in the negative L p ortion,
and when the centerpoint of the antenna trolley passes
across the zero line, the M arker 1 button has to be pressed.
The trolley is then pushed to the end of the scan. When the
stop acquisition button is pressed, the system automatically
associates a negative co-ordinate to the initial portion of the
file of the scan that has been performed
“
On
L/T coordinate
” selection
In this case, you have to manually measure the value of the
co-ordinate corresponding to the centerpoint of the antenna
array with resp ect to the reference system selected
previously, and insert it into the active field.
For example, if y ou have 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 this case. The scan can now be
performed.

4.6 Data acquisition
Once you are sure all the scan parameters have been correctly defined, you are
ready to start.
1.
Press the
button in the window shown in Fig. 4-27 and
start to move the trolley along the desired path (always in the same
direction). The results of the single sections will start to appear in real time
on the monitor in a window dedicated to channel 1 (see Fig. 4-31). The
active channel is indicated with a red box in the sweep window. When a
window is completely filled, the data will be written over from left to right
and you will notice that the content of the radar section changes line by
line. When the system passes across a possible utility or a radar target of
any type, typical hyperbola shaped figures will appear with variable
contrast in the depth direction corresponding to the impulses received. The
presence of targets can be detected by comparing these figures, window by
window, however, it is easier to perform this operation during the
processing phase. The distance travelled by the trolley (
Distance:….m
) is
shown above the radar map in real time, the depth is expressed in meters
(
m
) on the left y axis while the time delay expressed in nanoseconds (
ns
) is
given on the right y axis as indicated in Fig. 4-31. To visualize another
acquired channel in real time, you can click on the small window of the
signal corresponding to the desired channel.

If you move the trolley too quickly, an alarm sounds to warn you that you
are loosing data; if this problem continues, it is best to stop the scan with
the button shown in Fig. 4-31 and avoid saving the data
by pressing the
NO
button in the window shown in Fig. 4-32.
No modifications need to be made before repeating the scan apart from
returning the trolley back to the starting position.

continue to push the trolley in the same direction to the end of the scan,
then definitively save it using the above procedure. This save scan
procedure is particularly recommended for longer scans that may reach up
to a few hundred meters in length.
7.
By pressing the button, you cancel the last radar scan
performed. Once the radar map has been completely deleted, the
coordinates are updated to those of the preceding scan.
8.
Pressing the button terminates the acquisition phase,
then the software will save definitely all data storage of the same mission
by pressing the OK button in the window appearing (see upper

NOTE
Remember that data is grouped by scans, i.e. a group of radar sections
relating to a single passage of the radar trolley. Any group of radar
sections can be visualised from a given scan.
You have a list of names of saved scans available. The following
nomenclature rules apply for the scans:
1.
the scan file names have 8 characters and have the *.dt extension
before the data are processed;
2.
the filename is derived as follows:
•
1
st
character
L
or
T
depending whether the scan is
longitudinal or transversal,
•
2
nd
–3
rd
character can be chosen by the user,
•
4
th
character
*
= channel number used
•
5
th
–8
th
characters make up the progressive number of
the scan within the survey.
The first acquired file has the progressive number 0001, so for
example, the name LMA*0012.DT is the name of the twelfth scan,
performed in the longitudinal direction and contains unprocessed data.
Each channel has its own corresponding data file.
4.7 Operating in review mode
You can perform various operations on the acquired data. Once the acquisition has
been selected from the window shown in Fig. 4-33 (in the example shown here in

APPENDIX A - MECHANICAL REQUIREMENTS FOR THE
INSTALLATION OF SRS SYSTEMS ON BOARD A TRAIN
A.1 - Introduction
This section deals with the installation requirements for the use of a georadar
(GPR) system on-board a train.
The system consists of:
•
a notebook computer
•
a battery
•
a GPR control unit
•
a GPR multiplexer unit
•
up to 4 GPR antennas
•
an odometer
•
and relevant connection cables.
Items 1-4 will be mounted inside the locomotive and don’t need any specific
installation; on the contrary, items 5 and 6 shall be mounted in the front of the
train and require some mechanical arrangements.
For practical reasons (mainly logistical), some of the devices needed to assure the
proper mounting of the system should be provided by SNCF; basically, these
consist of a metallic frame used to house the antennas and the brackets for fixing
this frame to the front of the locomotive.
A.2 - Mechanical requirements
Mechanical installation of the antennas and the odometer requires brackets to be
fixed to the buffers of the train. Therefore, it is important that the train used for the
test has buffers.
Moreover, it is also important that there are no obstacles between the buffers as
measurements would be affected by them (see
Fig. A. 1
).

APPENDIX C - USING GPS WITH THE SRS SYSTEM
The SRS system can acquire GPS data in NMEA$GGA format. You therefore
have to set the GPS receiver so that the data output through the serial port or
Ethernet port is in NM EA$GGA format
.
The serial or ethernet communication between the GPS and the
Panasonic CF-30
notebook computer must be set up for GPS as follows:
•
Baud rate: 9800;
•
Byte size: 8;
•
Parity: No;
•
Stop bits: 1.
GPS data acquisition procedure with the SRS_PLUS system
:
Step 1
Connect the GPS receiver to the
Panasonic
notebook computer using the
serial cable shown in pictures Fig. C. 1.
Fig. C. 1 - Connecting the GPS to the notebook computer
Step 2
Open the
External device settings
after having clicked on the SRS
software icon at the top left of the main window (see pictures Fig. C. 2 and
Fig. C. 3).

/
76
Fig. C. 5 - Com settings window
For example, selecting External device type RS-232 GPS :
Select 1 in the
Com
menu (or set the number of the COM port
number the GPS is connected to) and the other parameters according
to the GPS characteristics;
Use the
Refresh rate
field in Fig. C. 3 to select the number of
sweeps interval the GPS data will be acquired with; for example, if
you have set the
Acquisition Step
to 2.4cm and the
Refresh rate
field to 20, the system will acquire GPS data every 48cm (2.4cm
*20=48cm); if the
Refresh rate
= 1, the SRS_PLUS system will
uptake all the information produced by the GPS according to the
time parameters set on GPS equipment.
Step 5
Accept the parameters set in the
COM settings
field by clicking the
OK
button, as shown Fig. C. 5.
Step 6
Correct functioning of the GPS and its communication with the
SRS_PLU S system is indicated by the GPS
spy light in the acquisition
window; when the light is green, the GPS is correctly connected and
functioning; when the GPS is red, either the connection between the GPS
and SRS_PLUS systems has not been correctly made or the GPS is
switched off (see picture Fig. C. 6).

WARNING
Remember that the GPS spy light only indicates the correct
functioning of the GPS, not the accuracy of the GPS readings; to
evaluate precision, use the tools supplied with the GPS system
Step 6
The GPS data in NMEA$GGA format are saved as an ASCII file in the
same directory as the radar data; the GPS files have the same numbering
as the radar files, but have a *.GPS extension (see the example shown in
the picture Fig. C. 7). During the radar data acquisition phase, you can
check the GPS acquisition data using white M arkers placed at the
bottom of the radar map.
