中文摘要： 多基地声纳探测能够改善检测性能，得到更高的估计精度，更大的探测范围，更好的稳健性。AUV具有灵活性、机动性和低成本性，借助AUV搭建的多基地声纳系统将是未来多基地声纳发展的重要途径。然而，水下环境复杂，声速较低，多普勒尺度远大于多基地雷达，多AUV联合目标探测的实用化还有很多问题急待解决。本项目拟在已有的研究基础之上，经过3年的研究，解决多AUV联合目标探测的若干关键技术问题：借助浮标作为参照物估计多AUV相对位置，基于多AUV的检测器数据联合进行目标检测，进一步研究基于多AUV的阵元原始数据来联合估计目标参数，并且评估多AUV相对位置误差对联合探测的影响并给出解决方法。通过大量模拟和仿真后，建立浮标+AUV的2节点实验平台，并搭载湖海实验，进行新算法的实验研究。通过此项研究，将大大提高多AUV联合目标探测的理论和技术储备，为实用化打下扎实的基础，为海洋监测和水下战术迈上一新台阶做出贡献。

英文摘要： Cooperative detection by multistatic sonar would lead to higher estimation accuracy, lager detection range, more robustness.The multistatic system composed of AUV will play an important part due to the flexibility, maneuverability, and low cost of AUV. However, the underwater environment with complicated space-time-frequency characteristics and random fluctuation, is more complex than in the air. Low sound speed makes much larger Doppler scale than multistatic radar, so that many problems restrict the practicability of copperative detection by multiple AUV. Basing on the past research, our program aims to solve several key problems for cooperative detection by multiple AUV by three years research, including AUV localization by sonobuoy, target detection basing on AUV detectors, and target parameter estimation basing on multiple AUV's raw signal. Moreover, the impaction of AUV localization error for target cooperation detection would be analyzed and the solution also provided. Lay on the foundation of algorithms and simulation system, a 2-node communication system is set up and composed of a sonobuoy and an AUV. The algorithms would be validated by numerical simulation, and lake experiment. The research will be beneficial to the applications of cooperative detection by multiple with theoretical and technical foun
