摘要
将模糊逻辑和IVI-CFAR检测器相结合,提出了模糊IVI-CFAR检测器。模糊IVI-CFAR检测器将两个统计量进行模糊化并选择对应的模糊检测器计算相应的隶属函数,然后传给融合中心,融合中心根据这些值采用本文提出的模糊融合准则进行判决。仿真结果表明:模糊IVI-CFAR检测器在均匀背景下与传统IVI-CFAR检测器有相近的检测性能;在多目标背景下和杂波边缘背景下检测性能有明显的改善,在实际检测中有更强的鲁棒性。
A new fuzzy IVI-CFAR scheme based on fuzzy logic and IVI-CFAR detector was proposed in this paper.Fuzzy IVI-CFAR established a new detection strategy based on the fuzzificastion of two statistics and selected the appropriate fuzzy detector to calculate the membership function value.Then send the value to a fusion center to make a decision which is propsed in this paper accroding to the fuzzy fusion rule.The simulated results show that the fuzzy IVI-CFAR detector have the similar detection perfor-mance compare with the classical IVI-CFAR detector in homogeneous environment.It has improved in non-homogeneous environ-ment significantly.It is more robust in practice.
