摘要：Signal processing in hydroacoustic system will be presented in this paper. The research results, depicted in this article, were achieved during realization one of the stages of the project for the development of an biomimetic underwater vehicle (BUV). The hydroacoustic system is installed inside Biomimetic Underwater Vehicle no. 2 (BUV2) and is designed for passive obstacle detection system. The passive measurement system was based on two hydrophones mounted on the upper part of the BUV2. The results of the hydroacoustic module testing were made in a real environment. The signals from the hydrophones were converted from analog to digital form and then fi ltered and analyzed by using algorithms implemented in the Texas Instruments C2000 series microcontroller.
