【Abstract】 Based on the advantage of variable step size LMS algorithm, a new algorithm of higher_order cumulate_based variable step quasi_LMS adaptive line enhancement is proposed. Simulation with the real data of a underwater moving target was carried out, the results show that the proposed algorithm has the ability to enhance and trace manifold frequency modulation signals. Accordingly, the research provides a new technical means for recognition and detection of the underwater moving_target.更多还原
