Abstract:
Radar countermeasure apparatus of the type in which a received radar signal is phase shifted by 180Â° prior to retransmission, comprising:antenna means adapted to be disposed at spaced apart location on a carrying vehicle for receiving radar pulses and retransmitting the same; first common channel means having switch means disposed at either end thereof, for, storing the received radar signal and for interconnecting the same to said antenna means; second common channel means having switch means situated at either end thereof, for storing the received radar signal and for presenting the same to said antenna means; pulse detector means responsive to the radar pulse received by said antenna means for alternating the interconnection of said first common channel means and said second common channel means so that a radar pulse is sequentially presented to one of said common channel means and then to the other of said common channel means; and pulse shift means connected to one of said common channel means for shifting the phase of one of said received radar pulses prior to retransmission by said antenna means.
