Yu Liu, Pei Li, Jinfeng Wang, Dengzhao Xie, Dongxu Jiang

Abstract

Due to integration of the frequency agility (FA) technology and coherent technology, Coherent FA radar has natural advantage in ECCM performance and represents one of important development trends of new radar types. Aiming at the technical characteristics of coherent FA radar, this paper proposed a jamming method to coherent FA radar based on intermittent sampling repeater. Theory models of coherent FA radar and intermittent sampling repeater jamming are established at first and the jamming effect is analyzed. The proposed jamming method is validated to be able to achieve the expected jamming effect to coherent FA radar by simulation at last.
