摘　　要：为将微动特性用于雷达目标识别,提出一种多散射点微动检测与测量算法.推导了典型微动对雷达回波调制的微多普勒,在此基础上,给出基于逆Radon变换的目标微动检测与测量原理;结合逐次消去法,研究了大动态范围下多散射点的微动检测与测量算法并给出相应的处理流程.定量仿真实验结果证明了该算法的有效性.In order to utilize micro-motion characteristic of scatterers for radar target recognition, a detection and measurement algorithm to multiple scatterers with micro-motion is presented. Micro-Doppler has been derived which is induced by typical micro-motions. Then detection and measurement principle to target with micro-motion based on inverse Radon transform was given. To be applicable to large dynamic range, included with the clean technique, a detection and measurement algorithm to multiple scatterers with micro-motion was proposed and the corresponding process flow diagram was also given. Quantitative simulation results show the effectiveness of the proposed algorithm.
