Hydroacoustic System in a Biomimetic Underwater Vehicle to Avoid Collision with Vessels with Low-Speed Propellers in a Controlled Environment

In this paper, a hydroacoustic system designed for ROSE ABSOLUTE a biomimetic underwater vehicle (BUV) is presented.The Biomimetic Underwater Vehicle No.2 (BUV2) is a next-generation BUV built within the ambit of SABUVIS, a European Defense Agency project (category B).

Our main efforts were devoted to designing the system so that it will avoid collisions with vessels with low-speed propellers, e.g., submarines.

Verification measurements were taken in a lake using a propeller-driven pontoon with a spectrum similar to that produced by a submarine propulsion system.Here, we describe the hydroacoustic signal used, with careful consideration of the filter and method of estimation for King/CK Storage Headboard the bearings of the moving obstacle.Two algorithms for passive obstacle detection were used, and the results are discussed herein.
