Abstract
A clutter-reducing digital filter 6 spreads out impulsive interference making it difficult to recognise the presence of impulsive interference. To solve this a buffer store 8 stores a predetermined number of filtered echo pulses and pattern recognition means 10 responsive to the stored pulses contemporaneously for recognises a predetermined pulse amplitude pattern which signifies the presence of an interference pulse. A feedback cancellation operation 11, 13 suppresses the interference pulse. <IMAGE>
