Abstract:
The detection performance of the traditional adaptive coherent detectors in nonstationary sea clutter is limited by the interference of strong sea clutter and the limited coherent integration time. To overcome the limitations, a subband segmented adaptive normalized matched filter (SS-ANMF) detector is proposed. It is composed by a linear phase discrete Fourier transform modulated filter bank and a segmented ANMF detector in each subband. Resorted to the subband decomposition in the frequency domain, the clutter in and out of the band is restricted and the shortterm stationarity of the clutter is enhanced. Besides, by summing over the maximum responses of segmented ANMF of all subbands within a cumulative time, the restriction from the sample size is lifted and the accumulated time is extended. The experimental results using real data show that the SSANMF detector outperforms the compared ones.
