| 中文摘要: |
| 结合水声对抗演练的实际需求,针对海洋环境下,目标定位困难且定位距离有限的问题,利用多水听器十字阵接收信号的加权,提高接收信号信噪比,达到定位目标的目的,通过波束形成和信号相关,依据目标方位与波束形成方位一致时能量最大的原则,实现对远距离目标方位和距离的估计,并通过仿真和试验验证,证明了定位方法的有效性。 |
| 英文摘要: |
| Taking into account the difficulty of position and its limited distance in marine environment, a seventeen-hydrophone cross array, which can improve the SNR of received signal by weighted all the channels, is designed to position the target combined with the actual demand in acoustic warfare exercises. According to the principle of that energy is maximum when the orientation of target and beamforming is consistent, the target is positioned by beamforming and signal-correlation. Finally, some simulation results and analysis of the method as well as experiment results are presented to verify the validity of the method. |
