Sea Clutter Suppression and Micro motion Target Detection in Sparse Do main
摘要
Abstract
Using the sparse property of the signal from a marine micromotion target,the extraction and detection of micromotion signatures in sparse domain are studied.An algorithm for sea clutter suppression and micromotion target detec-tion is proposed based on the morphological component analysis (MCA).The algorithm takes full advantage of the morpho-logical differences between sea clutter and micro-Doppler signal,and can separate them via sparse representation of different source signals using different dictionaries.Moreover,the proposed sea clutter suppression method in sparse domain can a-chieve both target’s energy accumulation and sea clutter suppression with improved signal-to-clutter ratio (SCR).Simulated and real data all verify the effectiveness of the proposed method.关键词
