中文摘要	In shallow water, in order to improve the passive sonar system's ability of target detection and parameter estimation, comb-spectrum signals was considered; it had better time delay and frequency shift joint resolution. but its Doppler tolerance is small, the traditional multimatch/ copy method need a large number of computation, considering the multi-peak structure spectral of comb signal, this paper proposed a novel detection algorithm based on frequency domain matched searching: use the difference between signal and noise in the frequency domain, to detecting signal and achieve velocity estimating. Simulation analysis showed that this method has the same detection result as matched filter. Copyright © 2014 by the International Society of Offshore and Polar Engineers (ISOPE).
