Extraction for Intra-pulse Characteristics of Multi-component LFM Signal Based on TFR-HT

CHENG Bo-lin1,YUAN Jun-quan2,MA Xiao-yan3(1.Department of Electronic Countermeasures,AFRA,Wuhan 430019,China;2.Department of Information & Command Automation,AFRA,Wuhan 430019,China;3.Division of Training,AFRA,Wuhan 430019,China)  
An improved method for extraction of multi-component LFM Signal intra-pulse characteristics was presented.By regarding the reassigned time-frequency distribution as an imaget,he signal intra-pulse characteristics of the multi-component LFMsignal were extracted respectively,based on the principle of detecting the line ofHough transform.The simulation results show that the proposed method can effectively extract each component intra-pulse characteristics of multi-component LFM signal,while it has better performance of anti-noise.
