Abstract

A high precision estimation algorithm for ground moving targets in multi-channel wide-area surveillance ground moving target indication systems is proposed based on maximum likelihood method. The main concept of this novel algorithm is to estimate the azimuth angle of the detected targets using maximum likelihood method with the space steering vector formed by the estimated interferometric phase extracted from the mainlobe clutter region of the real data. Through this novel algorithm, the effect of channel errors among the multi-channels can be well reduced. Simulation experiments demonstrate the effectiveness of the proposed algorithm.

基于最大似然法的多通道广域监控地面移动目标指示模式的高精度估计算法

基于最大似然法，提出了一种多通道广域监视地面移动目标指示系统中地面移动目标的高精度估计算法。这种新算法的主要概念是从真实数据的主波杂波区提取的干涉相位估计值形成的空间转向向量，利用最大似然法估计检测目标的方位角。通过这种新颖的算法，可以很好地减少多信道间信道误差的影响。仿真实验证明了所提算法的有效性。
