水下声学滑翔机海上目标探测试验与性能评估

针对传统海上目标探测效费比低且受恶劣海况影响严重的问题，亟需构建安全有效、多维立体的海上目标探测体系。水下声学滑翔机凭借其隐蔽性能好、环境适应强、成本低等优点，可广泛应用于海上目标探测。海上目标探测受海洋环境影响很大，需要进行系统、长期、深入研究。开展水下声学滑翔机海上目标探测试验并获取对不同海上目标的探测能力，是有效推进该研究的重要手段。该文重点围绕水下声学滑翔机对不同水面航船目标探测试验情况，从目标探测距离、目标估计方位精度和-3dB波束宽度三个方面进行了性能评估和总结。最后，对前期试验存在问题进行了梳理，并对下一步试验关注方向做了展望。 

Underwater acoustic glider target detection experiments and performance evaluation in the South China Sea

Aiming at the problem of target detection for traditional means with low-effectiveness ratios and severely affected by harsh sea conditions. It urgent need to build a safe and effective, multi-dimensional sea target detection system. Underwater acoustic gliders can be widely used in sea target detection due to their advantages of good concealment performance, strong environment adaptability and low cost. Sea target detection is greatly affected by the complex marine environment, and it is necessary to carry out systematic, long-term, and in-depth research. Carrying out underwater acoustic glider sea target detection experiments and acquiring detection capabilities for different maritime targets is an important means to effectively advance the research. This paper focuses on the performance of underwater acoustic glider on different surface ship target detection experiments, and evaluates and summarizes performance from three aspects: target detection distance, target azimuth estimation accuracy, and -3dB beam width. Finally, the problems in the previous trials were sorted out, and the focus of the future research directions was prospected.
