Clean方法逐次CFAR检测
Successive CFAR Detection by Clean Method
摘要
Abstract
Aiming to solve the masking problem of large target against weak target in the traditional CFAR detection algorithms,a successive detection method based on Clean theory is proposed.This method has three steps.First,the large target can be detected by employing any traditional CFAR method;second,the large target can be cleaned from the raw echoes by using the inversed waveform information;finally,the following targets can also be successively detected analogously.In this paper,the influencing factor of masking is analyzed,the analytic expression of target detection probability is deduced,and the related parameters performance is also illustrated.The validity is verified both by theory and simulation.The proposed method may bring forth some feasible suggestions in the field of detecting and resolving weak targets in the presence of closed spaced targets.关键词
