ABSTRACT:
In an active radar augmentation system a microwave switch is connected been the receiving antenna and the amplifier. When there is an RF input signal to the receiving antenna of the augmentation system, a square wave timing signal provided to the microwave switch is adjusted to have the microwave switch in an open state during a time period when the coupling or feedback signal from the transmitting antenna of the augmentation system is received by the receiving antenna. The "on-off" timing of the square wave signal is set equal to the external time delay of the feedback signal plus the internal time delay of the RF signal as the RF signal passes through the augmentation system. Under this condition, the feedback signal coupled by antenna leakage arrives at the output of the receiving antenna while the microwave switch is in the open state.
