The Radar Performance Monitor continuously monitors an ASR radar figure of merit, which is a function of the radar transmit power and the radar receiver sensitivity. The transmitted radar signals are received by the Monitor through free space RF coupling or direct connection to the radar, delayed in time, and retransmitted to the radar through the same signal paths. Through automatic adjustment of the retransmitted signal power from the monitor, a constant retransmitted signal to the radar system noise ratio at the radar video output is maintained. Any significant reduction of radar transmitted power and/or degradation of radar receiver sensitivity causes an adjustment of the Monitor retransmitted signal power level in order to maintain the same signal to noise ratio at the radar video outputs. When a preset Monitor retransmitted power threshold is exceeded, visual and aural alarms are activated. (Author)
