水下等离子体声源为一种强度高、宽带可控的脉冲声源，其声源级高于传统换能器，常被用作干扰远程目标的软杀伤性武器。当其产生的冲击波无法对目标实施有效的毁伤和干扰等软杀伤打击时，本文研究利用脉冲回波检测来对目标进行主动定位，以提升其运用效能。研究水下等离子体声源脉冲声波的有关特性，并对海底混响和海洋环境噪声与主动定位的关系进行相关仿真研究。建立以脉冲声波为主动声信号的目标主动定位处理模型，以舷侧11元阵和舷侧三子阵为接收水听器阵列，研究基于等离子体声源的主动目标定位技术，仿真验证了方法的有效性。
Underwater plasma acoustic source is a kind of high intensity, broadband and controllable sound source. Usually it has higher source level than conventional transducers. The location for the remote target can be realized through echo detection, when the high pressured pulse waves can not damage or disturb it. The property of the pulse waves produced by the plasma source, as well as the influence of the bottom reverberation and ambient noise on the active location, is studied by simulation. Based on the simulation results, an active positioning model is established, in which the plasma is used as the active signal. Finally, processing the signals received by the 11 elements broadside array and the broadside three sub arrays, and the performance of the active locating by plasma acoustic source is analysed.
