一种非均匀背景下的多策略CFAR检测器
Multiple strategy CFAR detector in nonhomogeneous enviroment
摘要
Abstract
For improving the detection performance of the radar constant false alarm rate( CFAR) in the nonhomogeneous environment,a multiple strategy CFAR( MS-CFAR) detector is presented here based on the variable index CFAR( VI-CFAR) detector. By estimating the background noise and the clutter power in the reference window, the MS-CFAR detector adaptively selects one appropriate detector from the cell average CFAR ( CA-CFAR ) , the approach cell CFAR ( AC-CFAR ) and the switching CFAR( S-CFAR) . The simulation results show that the MS-CFAR detector provides better detection performance in the homogeneous environment and the nonhomogeneous environment including clutter edges and multiple targets,and performs robustly with anti-clutter edges and anti-multi targets while maintaining the good performance of VI-CFAR detector.关键词
