ABSTRACT:
A technique for detecting and eliminating "sea-spike" interference in a rrn radar-signal. A series of signal delay means in cooperation with associated subtractors are utilized to detect particular sea-spike modulation interference frequencies. Detection of these modulation frequency components causes activation of means for preventing the sea-spike contaminated return signal from being further processed.
