C&I Jamming Technology Based on Frequency Diverse Array Antenna

Abstract

Chopping and Interleaving (C&I) interference can produce better jamming effect on pulse compression radar. Based on this, a novel radar jamming approach to utilize frequency diverse array (FDA) antenna is proposed in this paper. Compared with the traditional phased array antennas, there is a small frequency increment (δf) between each element of the FDA antenna, which provides promising prospect to develop new radar jamming techniques. The jamming approach proposed in this paper can quickly produce more false targets. Moreover, the number of false targets is manipulated by the elements and frequency offset of FDA antenna, which indicates that many false targets can be easy to control. The simulation results provide strong support for the effect of the proposed approach.
