Abstract
A sensitivity time control circuit for radar receivers, using range gated feedback where the video signal is sampled and compared to a desired signal at intervals based upon range sweep; as the radar antenna is reversing direction, integrated averages of the video signal are used to update the sensitivity time controlled waveform.
