一种复合高斯背景下存在干扰时的目标检测方法

A method for target detection in compound Gaussian clutter and interference

针对复合高斯杂波背景下存在干扰时的子空间目标检测问题,提出了一种自适应检测器.首先给出了该背景下目标检测的假设检验模型,然后根据两步广义似然比检验(GLRT)推导了该自适应检测器.相比常规自适应检测器,本文提出的检测器可在抑制干扰的同时提高目标的检测性能.仿真结果验证了该检测器的有效性.

This paper aims at the problem of subspace target detection in the presence of interference in the compound Gaussian clutter background to propose an adaptive detector.Firstly,the hypothesis testing model of target detection under this background is presented,and then the adaptive detector is derived based on the two-step generalized likelihood ratio test(GLRT).Compared with conventional adaptive detectors,the detector proposed in this paper can not only suppress the interference but also improve the detection performance of targets.Simulation results verify the effectiveness of the detector.
