FOD Finder Radar Calibration and Verification (cont.)
This reconstructed radar image of a runway relies on data processed using the calibration file;
data from bright point targets are used to verify that the calibration is current.
As part of system self-monitoring and self-calibration, the radar verifies the accuracy of its own
calibration by logging data from fixed point objects within the radar field-of-view and
comparing return levels to those measured at system installation. If it detects that these
returns have fallen below a threshold level, even after an attempted self-calibration effort, the
radar will alert the operator with an error message and request that the data be exported to
Trex Aviation for external re-calibration.
