Communication by radar sets - using radar location signals modulated with communication signals and transmitted by binary-coded, phase-shift keying

摘要

Radar transmission pulses with the communication are transmitter by binary-coded phase-shift keying. The modulated radar echo signals undergo asynchronous information cancellation in the video position before they are decoded in a permanent-echo filter. The information of the binary-coded radar echo signals may be cancelled as a function of time and information either by squaring the total radar echo signal or by summing the radar echo signals or by auto-correlation by specific pulse codes.
