| 中文摘要: |
| 本文分析了近场环境下基于双聚焦波束成形的水下被动测距方法。通过修正MVDR方向矢量,得到了适用于近场环境的MVDR。仿真实验证明近场MVDR双聚焦波束成形测距方法优于普通波束成形和远场MVDR双聚焦波束成形,能明显减小目标距离估计的模糊区域。在相邻两个日标的定位性能上,MVDR双聚焦波束成形技术也比MVDR单聚焦系统体现出更大的优势,能较好地分辨目标。 |
| 英文摘要: |
| In this paper, passive-range estimation is presented using near-field MVDR dual focused beamformers. Through modifying the parameters of MVDR, we obtain a method suitable for near-field condition. The simulation results show that the method is better than the conventional beamformer method and the far-field MVDR passive-range estimation method. By this method, the ambiguous area can be clearly reduced. |
