The Research of Dense decoy Target Generation and Feature Vector Extraction

Dense decoy target is a new type of active decoy jamming, which has been widely used in military field due to its excellent jamming effect. Based on this, the detection and recognition of dense false targets has quickly become the focus of research in the field of radar electronic warfare. In this paper, according to the generation mechanism of dense false targets, the working principle and advantages and disadvantages of DRFM are described, and then a method of combining antenna pattern function with radar equation to obtain target and jamming echo model is proposed. According to the actual situation, multiple groups of targets are set to obtain normalized and diffe-rential channel echo signals of each target.
