复杂背景下的二维检测研究

2-D Detection in Complex Background

由于雷达检测背景的复杂和起伏 ,经典CFAR检测不能保持稳定的检测性能。利用噪声和目标在距离 -多普勒二维平面上的信息构成特殊的二维窗 ,异常值剔除后进行二维窗的检测统计量计算。实验中 ,各种经典CFAR检测的稳定性和检测性能得到了不同程度的提高 ,本文提出的混合检测方式获得了最佳的检测性能。

Because of the complex and fluctuant background in radar, classical CFAR detection technology lose its stability. In this article, a special 2-D windows is introduced to ameliorate this problem after investigating the noise and target information on range-doppler plane. The test statistics is obtained after outlier elimination. In trial, performance of CFAR detect technology is improved and a new hybrid approach succeed.;
