非高斯杂波下雷达目标的检测

Detection of Radar Targets in Non-Gaussian Clutter

从非高斯杂波自身的特性出发，利用检测理论得到其最佳非线性检测器结构，并比较了它与Ｋ分布包络检测和经典高斯检测的性能。计算机模拟表明，其性能明显优于其它两种情况。另外，文中还就参数对检测性能的影响作了详细的分析。

In this paper,the non-linear detector structure based on detection theory is con-sidered according to the actual clutter characteristics. Performance comparision of the optimum de-tector with the K-distributed envelope detector and the conventional Gaussian detector is carried out.Computer simulation results show that the non-linear receiver significantly outperform the others.The influences of different parameters on the detection performance are also studied.
