密集多假目标干扰对CFAR检测影响分析
Impact Analysis of CFAR Detection for Dense Multiple False Targets Jamming
摘要
Abstract
The impact of dense multiple false targets jamming on radar constant false alarm rate detection is analyzed. Firstly, the generation principle of dense multiple false targets is introduced. Then, generation methods of dense multiple false targets jamming with three types of power modulation mode are given. Based on this, the detection cost caused by the false alarm and false dismissal in a search period of radar is chosen as the criteria of detection performance. The detection costs of cell averaging-constant false alarm rate( CA-CFAR) , order statistic-constant false alarm rate ( OS-CFAR ) .censored mean level-constant false alarm rate( CML-CFAR) under three types of dense multiple false targets jamming environments are analyzed. The simulation results show that detection cost is sensitive to the interval of false targets , and has little relationship with the power of false targets when dense multiple false targets exist. The detection cost of radar adopting CA-CFAR detector is lower than that of radar adopting OS-CFAR and CML-CFAR detectors.关键词
