MTI PERFORMANCE ANALYSIS IN NON-GAUSSIAN CLUTTER ENVIRONMENTS
非高斯杂波谱模型下的MTI性能分析

The MTI performance in non-Gaussian type clutter such as cubic and square clutter PSD (Power Spectrum Density) environments is analyzed. The up limit curves of the average improvement factor are given. Results show that the MTI performance in cubic or square PSD condition is much poor than in Gaussian. A measure for the clutter bandwidth is proposed in L2(R) space, which is more objective for evaluating the equivalence among the bandwidth of these three clutter PSDs. Finally, the curves of MTI performance degradation versus the MTI filter mismatch are presented, which shows that the performance degradation is insensitive to the mismatch only in cubic and square clutter PSD conditions.
