摘要

本文研究了稀疏平面天线阵在二维(方位角和仰角)到达方向估计中的优化问题。提出了基于峰值旁瓣电平(SLL)和半功率波束宽度(HPBW)参数的优化算法。在实证验证中，我们建立了一个测量系统来测试优化后的阵列配置的效率。阵列采用2.4 GHz频段贴片天线配置。实验结果表明，该天线阵与几种常用的阵型进行了优化，在二维方位估计中具有更高的精度和分辨率。

Optimization of Non-uniform Planar Antenna Array Topology in Two-dimensional DOA Estimation

The paper deals with the optimization of the sparse planar antenna array for direction of arrival (DOA) estimation in two dimensions (azimuth and elevation). The optimization algorithm was proposed on the basis of the peak sidelobe level (SLL) and half-power beamwidth (HPBW) parameters. In empirical validation, we have set up a measurement system to test the efficiency of an optimized array configuration. The array was configured using the patch antennas with frequency band 2.4 GHz. In comparison with several popular array configurations, the experimental results show that the proposed antenna array was optimized, and it provided higher accuracy and resolution in two-dimensional (2D) DOA estimation.
