A novel detection algorithm of LFM signal based on cubic phase function

摘要

Conventional electronic reconnaissance system has a difficult to detect wideband linear frequency modulation (LFM) signal, and the paper proposed a novel detection algorithm. First, estimated the parameters of LFM signal through cubic phase function (CPF) method, and then achieved the quasi-matched receiving of reconnaissance data. The experiments show that the proposed method can improve the performance of wideband LFM signals detection in low signal-to noise ratio (SNR) effectively.
