摘要

本文构建了一种特殊的天线阵列，在此基础上提出了一种与电子战环境相适应的极宽频段(2-18GHz)的到达方向估计方法。该方法通过在均匀线性阵列上添加适当的辅助传感器，克服了半波长间隔的限制。在空间亚奈奎斯特采样下，该方法提供了高精度的无模糊DOA估计。该方法不需要谱峰搜索和额外的配对算法，计算复杂度低。仿真结果验证了该方法的有效性。

The DOA estimation with spatial sub-Nyquist sampling based on an auxiliary sensor

In this paper, a special antenna array is constructed, then present a direction of arrival (DOA) estimation method for a very wide frequency band (2-18GHz) commensurate with electronic warfare environment. By adding an appropriate auxiliary sensor on a uniform linear array, the method can overcome the limitation of half wavelength spacing. Under the spatial sub-Nyquist sampling, the proposed method provides a high accuracy non-ambiguous DOA estimation. Also, the proposed method has a low computational complexity as it does not need the spectral peak search and extra pairing algorithm. Simulation results demonstrate the effectiveness of the proposed method.
