非高斯相关杂波下最佳、预测误差和平滑误差MTI的性能比较

Performance Comparision of OPT, PEF and SEF MTI in Non-Gaussian Correlated Clutter

根据白噪声检测理论，在白噪声中，检测信号通常先要进行“白化”处理。这里介绍了最佳（ＯＰＴ）、预测误差（ＰＥＦ）、平滑误差（ＳＥＦ）动目标显示器（ＭＴＩ）三种白化滤波器的基本关系，在非高斯相关杂波情况下，研究了它们在白化及检测方面的性能。通过计算机模拟表明，在实际雷达检测处理中，为了减少运算量及提高性能，建议选用ＳＥＦ或ＰＥＦＭＴＩ滤波器。

Based on the theory of detection in non-white noise, signals are usually whitened at first in the process of detection. In this paper, the basic relationship between OPT, PEF and SEF moving target indicator (MTI) whitening filters is introduced, and their performance of whitening and detection in non-Gaussian correlated clutter is studied. It is shown by computer simulation that in actual radar detection, SEF or PEF MTI filter is suggested to be selected in order to save the calculation time and improve the performance.
