ABSTRACT:
Undesirable signals which are similar to desirable signals occur in transmitter-receiver systems, phased array antenna systems and null or steering antenna systems and are eliminated by a novel adaptive processor. The undesired signal is electronically cancelled by causing the weak undesired replica signal to track the stronger undesired reference signal. The circuitry structure employs a phase tracking loop which generates a phase tracking error signal. The phase tracking error signal is applied to a voltage controlled oscillator and a fixed delay element in the phase tracking loop path. The phase tracking loop is coupled to the weak signal path to shift the phase of the weak undesired replica signal so that it is in phase with the stronger undesired reference signal and may be electronically cancelled. The system may be employed to eliminate undesired signals and leave weak desired signals uneffected and easily detectable.
