| 中文摘要: |
| 将最小方差无失真响应(MVDR)聚焦波束形成近场被动定位方法应用到平面任意结构阵列上,可以很好地解决线列阵由于阵长较长,在实际使用中存在布放困难、部分阵元失效影响定位性能等问题。本文首先分析了平面任意结构阵列的近场接收信号模型,推导出阵列流型,然后将MVDR聚焦波束形成技术应用到该模型中,得到了基于任意阵的MVDR聚焦波束形成近场被动定位方法。仿真验证了该方法的可行性和有效性。 |
| 英文摘要: |
| The appliance of the passive location method,using Minimum Variance Distortionless Response(MVDR) focused beamforming to the planar arbitrary geometry array can well solve the problem that the liner array has difficulty in the practical usage because of its long array length.The paper first analyses the model of receive signal in the near-field based on the arbitrary geometry planar array,and deduces the manifold.Next,it applies the MVDR focused beamforming passive location method to this model and obtains a MVDR focused beamforming passive location method which is applicable to the arbitrary geometry array.Computer simulation verifies the feasibility and the effectiveness of the method proposed in the paper. |
