Wavelet detection scheme for small targets in sea clutter

A radar target detection scheme based on wavelet determination of scatterer lifetime within the Doppler spectra of the non-Gaussian sea clutter was reported. It was demonstrated that the target detection was possible for slowly varying real target within the clutter spectrum based on a physical measure of scatterer lifetime. The method was found to be complementary to simple intensity thresholding when applied to be a low-observable time varying target.
