Adopting to the Root-MUSIC algorithm, a new evaluation measure based on array signal processing for acquiring azimuth of many independent target is presented. In the modern pulse radar, addition noise is not always Gauss noise, if a two rank evaluation is estimated, the error will be relatively larger. Simulated the signal of equal amplitude phase modulation, the better performance of the new evaluation is showed.

In this paper the imaging and location of multiple independent ground moving targets in a synthetic aperture radar system are studied. The algorithm based on the idea promoted by our research group is powerful to estimate the parameters of a single moving target, named target range history fitting, and now it is modified to make it suitable to estimate the parameters of multiple independent targets. Based on the estimated parameters a matched filter for each independent target is designed, and the all the moving targets are imaged simultaneously. The proposed method solves the problem that when one target is focused, others will blur. At last the parameter estimation precision and the factors that will affect it are analyzed.

针对合成孔径雷达正侧视工作体制下多个独立运动目标成像以及定位问题进行了研究。对经提出的运用距离历程拟合方法估计单个目标运动参数的算法进行了修正,准确地估计了t=0时刻各个目标的坐标和两维速度。基于估计的运动参数,设计各个目标独立的匹配滤波器,同时对运动参数不同的多个独立目标进行成像,解决了以往多个独立运动目标成像中的一个目标清晰成像,其它目标则会模糊的问题。着重分析了目标运动参数估计的精度以及影响估计精度的因素。
