Abstract
An incoming signal including the object signal and plurality of noise signals dispersed about the object signal is fully masked with white noise and applied to a phase synchronization loop wide in loop band width and including a local oscillator repeatedly swept by a sweep generator. During the repeated sweep a control signal generator successively decreases the level of the white noise until the oscillator is locked in the phase of the object signal. At that time the signal control generator is operated to suspend the sweeping operation and prevent the white noise from being added to the incoming signal.
