Abstract

A system for instrumenting time sampled interference suppression, particuly in a side-lobe canceller system. Interference signals are sampled just before a radar transmits on command of a sample gate or radar pulse, with main and auxiliary channel signals being delayed by the time between two successive samples. The two samples are then combined to allow interpolation such that weighting functions can be formed to adjust the delayed auxiliary signal so that interference in the delayed main channel signal can be suppressed at all times. By sampling just prior to radar transmission and interpolating between samples, cross modulation of clutter, and antenna scan error can be reduced in order that a side-lobe canceller system may be used compatibly with Moving Target Indicators (MTI).
