A Method of Counteracting Main Lobe Deception Jamming with Frequency Diverse Array

Abstract

In this paper, a jamming nulling method to counteract the deception jamming of the main lobe is studied. The radar adopts the frequency diverse array transmitting mode and the phased-array receiving mode. In this way, when the main lobe of the transmit beam pattern of the frequency diverse array is aligned at the desired target, the null is formed at other target positions. The problem that when using a frequency diverse array to identify a desired target, other targets can still jam the radar if they are on the high side lobe of the frequency diverse array beam pattern is solved. Computer simulation results show that the jamming nulling method adopted in this paper is feasible and effective.
