Abstract

Abstract:

Spread-Doppler clutter (SDC) caused by multi-mode propagation seriously affects the over-the-horizon radar (OTHR) detection performance for slow ships. To solve this problem, we propose to suppress multi-mode SDC using spatial information in the multiple-input multiple-output over-the-horizon (MIMO-OTH) radar system. Traditional processing algorithms need priori information of the target direction. However, it is often not readily available. And the clutter suppression effect could be unsatisfactory. In this paper, we propose a novel multi-mode clutter suppression algorithm based on the sparse signal reconstruction technology. The proposed algorithm only requires the dictionary for one-dimensional angle, which reduces the computational complexity compared to the conventional method using dictionary for two-dimensional angle. The estimated direction-of-departure (AOA-DOD) and direction-of-arrival (AOA-DOA) can be automatically paired. At the same time, we can obtain the time-Doppler information for the signal under each propagation path. The ideal MIMO-OTH radar multi-mode clutter suppression effect is obtained. Simulation results verify the effectiveness of the proposed algorithm.

Key words: MIMO-OTH radar, multi-mode propagation, clutter suppression, direction-of-departure estimation, direction-of-arrival estimation, sparse reconstruction
