基于模糊积累的宽带雷达CFAR检测

采用传统的统计检测方法进行高分辨雷达目标检测时不能充分利用目标回波的全部能量,影响雷达的检测性能.基于二进制积累检测方法和模糊检测理论,提出了两种模糊积累的检测方法,从理论上对所提方法的检测性能进行了分析;在均匀杂波背景和多目标背景、杂波边缘背景下进行了性能仿真.理论分析和仿真结果表明:模糊积积累检测方法检测性能比二进制积累检测方法的检测性能有明显改善,是一种稳健的检测CFAR方法.

CFAR Detection of Wide-Band Radar Based on Fuzzy Accumulation

The target echoes’energy can not fully utilized when adopting the conventional statistical detection scheme to detect the radar target with high resolution,which affects the detection performance of the radar.Based on the detection method of binary accumulation and fuzzy detection theory,this paper proposes two methods of fuzzy accumulation,analyzes their detection performance theoretically,and performs the simulation on their performances under the background of uniform cluster,multiple targets and cluster edge.Theoretical analysis and simulation results show that the performance of fuzzy accumulation detection method has a greater improvement over that of binary accumulation,and the latter is a robust method for CFAR detection.
