Synthesis of Arrays for Suppressing a Wide-Band Jammer

Abstract

This paper presents a design technique for a large antenna array to yield a pattern with low near-in sidelobes and a deep null in a specified direction. The performance of the array under wide-band operation and its effectiveness in suppressing wide-band jamming are investigated. Numerous transient patterns are plotted for various bandwidths and pulse-compression ratios. It has been found that, with a wide, deep null steered in the direction of jamming and by slightly increasing the rise time of the matched filter, the array is capable of suppressing an impulse jammer.
