摘要
基于声信标信号特征的快速识别技术、远距离微弱信号的快速定位技术、空域时域组合的多目标分辨技术,研发了基于圆型基阵的水下声信标搜寻仪“天科寻海一号”。通过消声水池、海上现场等试验,对其各项指标和整体性能进行了测试。该设备探测距离达3000 m、方向分辨力达0.5°,具备同时搜寻多个声信标的能力。通过实时交会定位方法,可对大面积海域进行快速搜索及准确定位,具有重要的工程应用价值。
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 3000 m,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.
