Based on the existing marine environment observation buoy platform, a "G-Argo" underwater acoustic buoy with target detection ability was developed. To verify the acoustic detection performance of the acoustic buoy platform, in May 2018, a sea trial of multiple underwater acoustic buoys was organized in the South China Sea. During the trial, the test ship and the sea passing ship were used as the detection targets.The test results show that, under good hydrologic conditions in the deep sea, the maximum detection distance of the underwater acoustic buoy to the coordination test ship with a speed of 10 kn is longer than 14.4 km,and the maximum detection distance to the target of the engineering ship with a speed of 6.4 kn is more than 42.8 km. The farthest detection distance to the target of the container ship with a speed of 12 kn is more than15.8 km, and the furthest detection distance of container ship target with speed 14.5 kn is greater than 24 km.It is verified that the "G-Argo" underwater acoustic buoy has good detection performance for maritime target.
