Space-Time Adaptive Processing Used for Underwater LFM and CW
In order to use the STAP in reverberation suppression,and compare the performances of STAP for underwater LFM with CW,the method of STAP used for LFM was proposed.Firstly,the principle of STAP for CW was analyzed,according to the underwater echo of CW.Then,the space-time steering vector of LFM is deduced by analysing the underwater echo ofLFM.Fianlly,the performances of STAP for LFM and CW were compared by simulations.The results show that the proposed method of STAP for underwater LFM with narrower modulation bandwidth can achieve a better performance in target detection and estimate,and the processing gain of STAP for CW is higher than that of LFM form 1.6dB to 5.5dB with the modulation bandwidth from 100Hz to 600Hz.
