Abstract

PURPOSE:To execute simultaneously both an active and a passive mode and to detect a target precisely by separating the signals received by both modes through a limiter and a BPF. CONSTITUTION:A transmit signal sent from a transmitter 2 by a trigger signal of a synchronizer 1 is reflected by a target and its received signal is inputted to an amplifier 10 through a mixer converter 5 and a BPF7. A radiation signal from the target, on the other hand, is also inputted to the amplifier similarly. Both signals are summed up by the amplifier 10 and inputted through a BPF8 to an amplitude detector 11 to detect the target in active mode. Further, it is inputted to an amplitude detector 15 through the limiter 13 of the amplifier 10 and a BEF14, and its amplitude detection output is smoothed 12 to detect the target in passive mode.
