Research on Underwater Acoustic Environmental Perception Based on Sparse Channel Estimation

In the exploration of ocean resources, underwater perception has become an indispensable tool. This paper proposes a comprehensive approach for underwater environmental perception that utilizes channel estimation to account for multipath effects and direction of arrival (DOA). We initially introduce sparse channel estimation with multipath effects, and subsequently delves into DOA analysis. We explore environmental perception based on both sparse channel estimation and DOA estimation. Both simulations and experiments validate the effectiveness of our proposed method, demonstrating its practical applicability.
