Maritime Radar Target Detection in Presence of Strong Sea Clutter Based on Blind Source Separation

ABSTRACT The study presented in this paper falls within the scope of the target detection problem in presence of clutter. The authors propose to use the complex-valued spatio-temporal FastICA (CSTFICA), which is categorized in the field of blind source separation (BSS), under the observation of the marine environment by a fixed monostatic maritime radar in order to separate the useful signal (derived from the target) and the resulting noise of the sea clutter. Tests using IPIX radar data and simulated target verify the performance of the method. The results show the efficiency of the method in different situations. Also, the superiority of the method in comparison to other existing methods such as the block adaptive normalized matched filter detector is shown by the result.
