Underwater acoustic glider, target underwater acoustic signal detection in water and gestures sense of three dimensional composite with vector hydrophone of co-vibrating type application requirements, design a kind of application in underwater acoustic signal detection of underwater acoustic glider system, the system has low noise, high cost-effectiveness ratio, low cost, low maintenance cost and reusable, profile gliding way can be used to collect information environment noise and moving target radiated noise.The data acquisition and real-time analysis unit of the acoustic detection sub-system of the underwater acoustic glider adopts the design scheme of FPGA+DSP architecture to control the attitude sensor to collect the attitude information of the vector hydrophone in real time and complete the joint signal processing of the underwater acoustic information and attitude information.The test results show that the acoustic system of the underwater acoustic glider can collect underwater acoustic signals within a range of 100～3000Hz. In the deep sea, the hydrology environment is favorable, and the working mode of profile gliding is adopted to detect the vessel with a length of 42 meters, a width of 6 meters and a speed of 8.4 water-saving surface. The vessel's detection distance is ≥7.8 kilometers.
