| 中文摘要: |
| 矢量互质阵是一种能分辨左右舷、成本较低且方位分辨力较好的稀疏阵，但方位估计时会产生高旁瓣干扰和方位模糊。利用时延求和虚元内插可以改善有关问题，本文提出一种基于虚元内插法的互质阵波束形成方法，首先仿真分析产生测向干扰的原因，其次通过仿真模拟和海试数据处理获得方位历程结果，验证新方法的可行性和实用性。结果表明：新方法能够抑制上述测向干扰，改善矢量互质阵测向性能。 |
| 英文摘要: |
| Vector coprime array is a sparse array with low cost and good azimuth resolution, it can distinguish the starboard side. However, high side lobe interference and azimuth ambiguity can be generated when it estimates the target orientation. The problem can be improved by using delay summation virtual element interpolation. In this paper, a method of beamforming for coprime array based on virtual element interpolation is proposed. Firstly, the causes of direction-finding interference are simulated and analyzed. Secondly, the results of bearing time record are obtained through simulation and sea test data processing to verify the feasibility and practicability of the new method. The results show that the new method can suppress the direction-finding interference and improve the direction-finding performance of vector coprime array. |
