Title: Beacon-on-demand radar transponder

Abstract: A radar transponder is provided that synchronizes the encoding of repeated radar pulses using an envelope detector to detect the envelope of received radar pulse signals. An edge detector detects the pulse edges in the envelope so that code words may be multiplied with the received radar pulse signals synchronously with the detected pulse edges to provide an encoded pulse train that may be transmitted to a radar interrogator.
