摘　　要：针对海上目标探测问题,将矢量水听器和Argo浮标相结合,可构建一种具有水中目标探测能力的新型水下声学浮标平台。该浮标平台可多次上浮和下潜,具有在位时间长、隐蔽性能高、成本低等特点,单台水下声学浮标即可实现海上目标探测,利用多台水下声学浮标可快速形成大面积区域覆盖能力。为进一步验证水下声学浮标对海上目标探测性能,2019年8月在南海海区开展了多台水下声学浮标海上试验,数据处理结果表明:南海夏季典型声速剖面下,水下声学浮标对船长42m航速8.4kn的水面航船目标最远探测距离可达13.8km,目标估计方位均方根误差最优可达5°,在水面航船距离最近的1.9km处,目标估计方位标准差可达2°。A new type of underwater acoustic buoy platform with target detection capability has been developed by combining vector hydrophone with profile buoys.The acoustic buoy can achieve multiple floating and diving,and has the characteristics of long in-position time,high concealing performance and low cost.The use of multiple underwater acoustic buoys can quickly form a large area coverage.To verify the underwater acoustic buoy’s detection performance on ocean targets,a large scale underwater acoustic buoy platform trial was carried out in the South China Sea in August 2019.The results are as follows:under the typical sound velocity profile of the South China Sea,the acoustic buoy has a maximum detection distance of 13.8 km to the surface vessel with a length of 42 m and a speed of 8.4 kn.The root mean square error(RMSE)of target estimated azimuth can reach 5°,and the standard deviation will be up to 2°when the distance between the acoustic buoy and surface vessel is less than 1.9 km.
