摘要
目标微动特征提取是当前研究的一个热点,在组网雷达技术中研究了旋转目标的微多普勒效应,分别分析了组网雷达中不同信号形式下的目标微多普勒效应,并给出了其参数化表达。利用组网雷达的多视角特性,将不同信号形式下分布在不同位置的雷达获得的回波信号进行参数提取,通过构造多元非线性方程组,以提取的参数作为变量,进行目标3维微动参数解算,实现了目标3维微动特征的提取。仿真实验验证了所提算法的有效性。
：The micro - motion feature extraction for micro - motion target has attracted great attention in recent years. The micro - Doppler （ m - D） effect of per. The m- D effects are separately analyzed that transmit different forms of signals. Making rotating target is introduced in the netted radar techniques in the pa- and the parameterized expressions are deduced in the netted radars use of the multi - view of netted radar, the parameters of the radars ＂different forms of echo signals those come from different locations are extracted, the three - dimensional micro - motion features are obtained by solving nonlinear multivariable equation systems. Simulation results validate the ef- fectiveness of the proposed algorithm.
