| Abstract: | Underwater acoustic beacon locator has been developed based on the fast recognition technology of acoustic beacon signal characteristics,the fast positioning technology of remote weak signal,the multi-target resolution technology of spatial and temporal combination.In this paper,the performance indicators of the equipment are tested through experiments of anechoic pool and offshore field.The detection distance of the equipment is up to 3000m,and the direction resolution is up to 0.5°.It has the ability to search multiple acoustic beacons at the same time.Through real-time intersection positioning,it can quickly search and accurately locate acoustic beacons at a large sea area,which has important engineering application value. |
