These parameters are modified when the system software is updated with the system maintenance tool. The User may also exit the SIR 30 program through this menu. Figure 61: DSP configuration.
  • Page 48 Gain is signal amplification used to counteract the natural effects of attenuation of the transmitted signal as it propagates in the media. The SIR 30 allows the user to apply a Time Variable Gain (TVG) function to the radar signal. Gain may be applied between 1-8 evenly spaced locations along the selected time range.

  • Page 50 SIGNAL PROCESS > IIR FILTERS The SIR 30 system utilizes both IIR and FIR vertical and horizontal filters for noise reduction and signal conditioning. IIR stands for ‘Infinite Impulse Response’. These are a class of digital filters that have an impulse response function that is non-zero over an infinite amount of time.
  • Page 51 User should consult their horn antenna manual for instructions on how to use the custom filter creation tool. The User must copy the *.CSV Custom filter file into the FILTER folder on the SIR 30 or use the SIR30 MaintenanceTool. The FILTER folder is located on the SIR 30 server under: \GSSI\SIR30\FILTERS.
  • Page 52 This filter is very useful for removing flat, horizontal noise bands in the data. This filter value should be set very high. GSSI recommends that a value of 1023 scans be used when running a FIR background removal.

This changes how the radar signal amplitudes are mapped to the color table indices. Figure 70: Color Transforms.
  • Page 55 Geophysical Survey Systems, Inc. SIR® 30 Manual OUTPUT OPTIONS > DISPLAY > DISPLAY GAIN The option allows the User to apply a display gain to the data during data collection. The display gain is a unity (1 point) gain. The values are expressed in dB. The User may increase or decrease the display gain. The User may change the display gain on the fly during data collection or data playback.
  • Page 56 Geophysical Survey Systems, Inc. SIR® 30 Manual Figure 73: Channel Split Scaled- Time. With the channel split set to SCALE and the vertical scale units set to Time, the vertical scale of the channels are scaled relative to the maximum time range selected (Figure 73 above). If the User has the system units of the vertical scale set to Depth, the display will scaled based upon the value of the Dielectric Constant set in the Radar CONFIG menu (Figure 74 below).
  • Page 57 The fifth major tick lines up with the distance mark placed in the data at 5 meters as per the parameters set the Distance Control System Settings menu (Figure 75 above). GSSI recommends that when collecting data using metric units to set the scan parameters such that the Scans per Unit divided by the Ticks per Unit is a whole number and to set the Ticks parameters such that the Ticks per Major Tick divided by the ticks per unit is a whole number.
  • Page 58 Geophysical Survey Systems, Inc. SIR® 30 Manual display. Other ratio’s of Scans per Unit, Ticks per Unit and Tick per Major Tick may be more (or less) useful. In the example below we have set the Scans per Meter to 100, the Ticks per Unit to five (5) and the Ticks per Major tick to five (5) which results in the distance scale in Figure 77 below.
  • Page 59 (1) will generally not yield satisfactory results unless the Units per Mark is large (> 5 ft). GSSI recommends using Ticks per Unit values that are less than or equal to one e.g. 1.0, 0.1, 0.2, 0.3, etc., when operating with English units.
  • Page 60 ‘roomy’ horizontal scale display which aligns with the distance markers on the radar data. Note: When operating the SIR 30 at very high scan rates, the SIR 30 will compress the display by a factor of two (2) at 200 scan\sec increments. E.g. at 200 scans\sec the scale is compressed by two (2), at 400 scans\sec the scale is compress by four (4) and so on.
  • Page 61 COPY/MOVE TO LAPTOP: These options will only be visible if the User is running the SIR 30 from a laptop. All data is stored on the SIR 30 internal hard drive. The data will have to be copied or moved to the laptop before they can be reviewed or processed in RADAN 7.
  • Page 62 This option allows the User to change the Depth/Distance units and to display the vertical scale as either Time or Depth. If the User specifies Depth Scale > Depth, the SIR 30 will use the Dielectric Constant specified by the User in the RADAR CONFIG\SCAN menu to perform the time to depth calculation.

By default, he SIR 30 load the last value used for samples per scan. The first time that a User connects a specific antenna to the SIR 30 and selects the default setup for the antenna the value loaded for the samples per scan is 256.

    SIR® 30 Manual Appendix F: SIR 30 Wiring Instructions The SIR30 runs with a DC input from +10VDC to +28VDC. It will not turn on unless there is a minimum of +10V at the power connector. The system will shut down immediately if the input drops below +9V under load.
  • Page 142 If custom wiring is to be used to power the unit in a +12V application the wire must be rated for 30A and all 4 INPUT terminals wired. The GSSI cable uses 4 x 12AWG stranded conductors and this should be suitable for 20 feet of cable length.
