1. An interference suppression system for use in high clutter environments comprising:

  • main channel means for receiving desired and interference signals and providing a main channel signal;

    auxiliary channel means for receiving primarily interference signals and providing an auxiliary channel signal;

    first means coupled to said main and auxiliary channel means for correlating the interference signals to produce phase and amplitude correlating weights;

    second means coupled to said first means for repetitively sampling each of said weights and combining said samples to form instantaneous phase and amplitude predicting weights;

    third means coupled to said second means and said auxiliary channel means for combining said predicting weights and translating said auxiliary channel signal with said combined weights to provide a cancelling signal; and

    means coupled to said third means and said main channel means for subtracting said cancelling signal from said main channel signal to thereby reduce interference.
