摘要 该文首先对国内的几种GMTI系统动目标处理性能进行了简单分析,接着给出了一种以杂波抑制干涉(CSI)算法为基础的机载三通道GMTI信号处理方法及处理流程。然后根据几何关系分析了杂波抑制原理,并结合实际飞行情况给出一种基于最小功率准则的通道补偿相位自适应对消方法。最后分析了动目标干涉相位定位和测速相关问题,实际试验结果表明该方法有效。 In this paper, the performance of several China GMTI systems is briefly introduced at first. After that, a method is prompted based on CSI algorithm for air-born three-channels GMTI signal processing. The processing diagram of this method is given, the principle of cluster suppress is analyzed, an adaptive phase compensation method for each channel is presented based on the minimum power criterion and the locating and velocity- estimation problem of moving targets is analyzed. The actual experiment result show that the presented method is efficient.
