Abstract: A passive acoustic localization method and a district control method are proposed based on cross-spectrum time-delay estimation method and principle of triangulation localization in order to effectively detect an underwater target and accurately estimate its direction under long distance and low signal-to-noise ratio(SNR), and are verified by simulation, anechoic tank test and the data of real ship. The results show that the proposed methods are simple and operable, and have a good engineering application prospects.
