Abstract

Abstract:

It is always a difficult task for the marine surface surveillance radar to detect the floating small target embedded in the sea clutter. Considering the non-uniform and non-stationary nature of sea clutter, the block-whitening strategy is used to suppress the clutter. By analyzing the differences between the energy distributions of the clutter-only returns and those of the returns with the target in the time-frequency (TF) plane, a TF feature is extracted via the TF-ridge-aided Hough transform. A detector using the TF feature is proposed. Experimental results for the IPIX radar datasets show that the proposed detector attains a better detection performance than the fractal-based detector in a relatively short observation time.

Key words: floating small target, sea clutter, block-whitening, Hough transform, IPIX radar
