摘要

本文提出了一种基于有序统计(OS)的VI-CFAR检测器(OSVI-CFAR).在均匀杂波背景下OSVI-CFAR较基于均值水平(ML)的VI-CFAR检测器(MLVI-CFAR)有较小的CFAR损失

在杂波边缘背景下二者的虚警控制能力基本一致

但在多个干扰目标位置随机分布的背景下检测性能较MLVI-CFAR取得了较大改善

在实际杂波环境中具有更强的鲁棒性.最后给出了OSVI-CFAR检测器的一些重要特性.

Abstract

A robust VI-CFAR detector based on ordered statistic (termed OSVI-CFAR) is presented.In homogeneous environment

the OSVI-CFAR has a low-loss compared with the VI-CFAR based on mean level (termed MLVI-CFAR).In clutter edge environment

the false alarm performance of this detector is almost consistent with the MLVI-CFAR detector.But in the situation that the interfering targets are located in reference window stochastically

the detection performance of the proposed detector is improved greatly.So it is more robust than the MLVI-CFAR in practice.Finally

some important properties of the OSVI-CFAR detector are indicated.
