非高斯背景下基于ODV的距离扩展目标检测器
Range-Spread Target Detector Based on ODV for Non-Gaussian Clutter
摘要
Abstract
This paper addresses range-spread target detection in spherically invariant random vector clutter. The modified scatterer density dependentMSDD)detector is introduced, and the analytic expression relating false alarm probability to detection threshold is deduced. MSDD need to estimate the number of scatterers, and its performance degradation gracefully when there is a mismatch.To improve the robustness of MSDD,a detector based on ordered data variability(ODV)is proposed. The results show that ODV-MSDD is robust for various target range extent, and its detection performance is improved when increasing the number of scatterers, sensors and spiky of the clutter. Compared with the MSDD, ODV-MSDD estimates the number of scatterers adaptively, and it can improve performance and robustness of detector effectively.关键词
