Application of Dual-Threshold Detector in Wide-Band Radar CFAR Detection

The dual-threshold detection used in low resolution radar and the characteristics of high resolution range profile of wide-band radar are discussed.A new application of the dual-threshold detector in wide-band radar detection is derived.Based on many successive profiles within a small angle,this method overcomes the shortcoming of the dual-threshold based on single profile and takes effective use of the information of many profiles.Simulation results show that the method has good performance and possesses good robustness for range profiles of different angles.
