中文摘要：
通道频带失配严重影响着空时自适应处理（STAP）的性能,定量地了解通道频带失配对STAP性能的影响对于工程实际有重要意义,本文基于现有的通道频带失配模型,从理论上推导了存在通道失配时和与无通道失配时的杂波协方差函数之间的关系,并分析了通道失配对目标信号的影响,最后针对不同的失配参数对STAP性能的影响进行了仿真分析,并利用两种均衡方法给出了均衡后的结果。
英文摘要：
Channel mismatch, including amplitude and phase mismatch, has severely affected the performance of space-time adaptive processing （STAP）. In order to ascertain the specification of the effects on STAP, theory analysis of relation between clutter covariance function （CCF） with and without channel mismatch is done based on the existing model provided by literature, and the effect to signal is also analyzed. In the end computer simulation about the STAP performance is done according to different channel mismatch parameters, and the corresponding equalization results are presented by employing two existing equalization methods, and useful conclusions are received.
