摘　　要：多目标方位估计(DOA)是水下进行目标探测的关键技术。高分辨目标DOA算法具有良好的工程应用前景。在水下多目标DOA的多处理器硬件平台上,实现了基于特征分解的多种高分辨DOA算法,并用水池实验数据进行了仿真研究,对算法的运算时间和方位估计的性能进行了分析。实验结果表明,系统能够实时完成高分辨DOA算法,波束域方法比阵元域方法性能优越,具有良好的方位估计性能和实时处理能力,满足了工程技术要求。Multi - target direction - of - arrival （DOA） estimation system is the key technique to underwater target detection. High- resolution DOA estimation algorithms have a promising future in engineering application. On the platform of multiple processor hardware for underwater multi - target DOA, several algorithms based on eigende- composition are implemented. Simulation experimental study based on pool experiment data is made to analyse the operation time and the performance of DOA estimation. Simulation results show that the system can realize the beamspace high -resolution DOA algorithm in real time, and the algorithm in beam domain is much better than the ones in array domain. And the system has good performances of DOA and real time processing, and can satisfy the engineering requirements.
