Abstract
Frequency diverse array(FDA)radar achieves spatial-frequency two-dimensional modulation by introducing frequency offset,demonstrating higher flexibility than traditional phased array radar.In view of this,the paper conducts the research on the interference characteristics of the FDA jammer.Firstly,the paper overviews the fundamental principles of FDA radar,including its basic concepts,beam characteristics and system architec-ture,then analyzes the mechanism of FDA jamming techniques,and elaborates in detail that the FDA jamming sys-tem achieves effective jamming of the enemy radar system through a three-level processing link of signal intercep-tion,reconstruction and jamming implementation.Finally,simulation analysis is carried out to verify the superior performance of the FDA radar in terms of beam characteristics,jamming signal effectiveness and false target gen-eration.关键词
