IDS Ingegneria Dei Sistemi S.p.A.  Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software   34 / 76 4.2 Choosing the configuration The  steps to  be  followed  for  choosing  the  required  radar  configuration  for  the acquisition are given below. 1. Press the   button (Fig. 4-2) to open the Radar selection window  (Fig.  4-3).  This  is  where  you  can  choose  the  antenna  type  and configuration  for  the  acquisition.  In  the  example  shown  in  Fig.  4-3,  the user has choosen a configuration file from the list. This file corresponds to an array of 3X400M Hz antennas. Naturally the user can choose different  types  of  configuration  for  the  SR S_PLUS  sy stem,  as  shown  in  Fig.  4-3, selecting a configuration of between 1 and 3 antennas.   Fig. 4-3 – Radar selection window   2. The range  can be changed with respect to the preset value by typing the new value in the Range field (Fig. 4-4).   Fig. 4-4 – Range field
IDS Ingegneria Dei Sistemi S.p.A.  Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software   35 / 76 3. The  number  of Samples  per scan  can  be  varied  by  choosing  one  of  the preset values available  in the Sample per scan field (Fig. 4-5). However, this  value  can’t  be  lower  than  the  one  indicated  in  the Min  req. sample/scan.   Fig. 4-5 – Samples per scan  4. The  electromagnetic  wave  propagation  speed  can  then  be  set  in  the Propagation  speed field  (see  Fig.  4-6).  We  recommend  you  accept  the default value unless you have specific information on the types of ground present in the area to be investigated.   Fig. 4-6 – Propagation speed field  4.3 Setting up the Calibration This paragraph  describes  the procedure  used to  calibrate  the p arameters  used  in the real-time processing of radar data. 1. Press the   button shown in Fig. 4-2 to view the window shown  in  Fig.  4-7,  then  p erform  the  automatic  calibration  p rocedure  by  moving the antennas across the surface to be scanned for a distance of at  least one meter. 2. Stop the calibration phase by pressing the   button in the window  shown  in  Fig.  4-7.  This  permits  the  system  to  save  the  filter parameters required to view the radar map s in real time.

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
IDS Ingegneria Dei Sistemi S.p.A.  Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software   49 / 76 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 =  0;+2 m, the following values must be set: • Longitudinal; • 2 in the Coord value field; • 2 in the Coord. Step  field. Once  the  scan  is  finished,  the  coordinate  of  the  L  v alue  is  automatically positioned on the value 4.    !  BE CA REFUL   The  Antenna  array  may  only  be  moved  in  one  direction.  It  may  only  be pulled  or  pushed  in  the  direction  of  increasing  scanning  coordinates,  the only exception being when the Inverse Direction field is activated.  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.

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 1st 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.    !  BE CA REFUL   In  “With  1st  marker  1  step”  mode,  the  antenna  system  must  be  moved  at least 20 cm after having pressed the Pos. Marker button shown in Fig. 4-29 before pressing the stop button; otherwise the section cannot be viewed by  the elaboration SW.

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.

When you want to save the acquired data on the disk, you can choose to press the   button shown in the window in Fig. 4-31, then create the temporary file by pressing the YES button in the window in Fig. 4-32. 6. But you can also choose to temporarily save the data acquired up to that point  by  pressing  the    button  shown  in  Fig.  4-31,  and 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 Fig. 4-33); then  you  move  on  to  the window  shown  in  Fig.  4-33  which  has  all  the review functions activated.

IDS Ingegneria Dei Sistemi S.p.A.  Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software   55 / 76  ! 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: • 1st  character L  or T  depending  whether  the  scan  is longitudinal or transversal, • 2nd –3rd  character can be chosen by the user, • 4th  character * = channel number  used  • 5th  –8th  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 Fig. 4-33, the Acq acquisition is chosen) you can: 1. Press the   button shown in Fig. 4-33 to view the selected acquisition.  The  first  radar  section  of  the  selected  scan  will  appear  (Fig.  4-34). From this section, once the Edit parameters button has been pressed, it  is  then  possible  to  modify  the File  prefix field and  the Longitudinal/Transversal field shown in Fig. 4-35.  You can select another scan belonging to the same acquisition directly from the window shown in Fig. 4-34, choosing the one you want from the text box shown in Fig. 4-36 or by pressing the   and   buttons to view the next or previous scans respectively.

Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software   62 / 76 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).
