基于随机PRI压缩感知雷达的速度假目标识别方法
Velocity False Target Identification Based on Random Pulse Repetition Interval Compressed Sensing Radar
摘要
Abstract
When the random pulse repetition interval (RPRI) compressed sensing radar suffers from the jamming of active velocity false target,the sparsity of target echoes will be destroyed and the RPRI compressed sensing radar's superiority on target detection and velocity measurement will be limited.In practice,due to the random modulation,the jammers can hardly update precise parameters such as the random PRI in time,which will induce the echo signals of true and false target to be sparse in different dictionaries.By utilizing this factor,a velocity false target identification algorithm is proposed within the frame of compressed sensing.The echo signals of true and false target can be sparsely presented and separated by building a joint dictionary.Also,to present application limitation of the algorithm,the autocorrelation of the joint dictionary under different RPRI signal's random mode is analyzed as well as its influence on the separation results.Computer simulation verifies the effectiveness and superiority of the algorithm.关键词
