Abstract
A sampling repeater includes a transmit/receive switch for inputting a received RF signal to a delay line. The delayed signal is then scrambled and fed to the transmit/receive switch, which changes its state so as to transmit the scrambled signal with minimal delay. A delay-stabilized oscillator is connected across the delay line and generates a control signal to produce a sampling waveform for the incoming RF signal. This waveform also synchronizes the transmit/receive switch so that the circuit becomes self-synchronized. The end result will be transmission of a scrambled incoming signal which will adversely affect the guidance of an incoming missile being guided with the RF signal simultaneously picked up by the repeater.
