| 摘 要： | 通道失配严重影响着空时自适应处理(STAP)的性能,定量地分析通道失配对STAP性能的影响对于STAP算法的工程应用具有重要意义。文中根据通道失配是否依赖于到达角、信号带宽是否为窄带等方面,从理论上推导了存在通道失配时的杂波协方差矩阵,并仿真分析了通道失配对STAP性能的影响,为STAP算法理论建模、STAP系统设计提供理论依据。

| Abstract: | Channel mismatch seriously affects performance of space-time adaptive processing (STAP), so quantitative analysis of its effect on STAP performance is significantly important for engineering application of STAP. With respect to such problem that whether channel mismatch depends on the angle of arrival (AOA) and is narrow-band or not, clutter covariance matrix (CCM) with channel mismatch is theoretically derived, and the effect of channel mismatch on performance of STAP is also analyzed. The work in this paper can provide theoretical support for STAP algorithm modeling and STAP system design. |
