| 摘 要： | 该文针对近场源的方向角和距离的二维参数估计，提出了一种新的近场源二维参数估计方法。该方法利用双极化阵列的极化信息和二阶统计量估计近场源的波达方向和距离参数。该方法具有估计精度高和无需谱峰搜索的优点。仿真实验证明了该算法的有效性。

| Abstract: | The bearing and range estimation of near-field sources is studied and a new method is presented. The presented algorithm uses the dual-polarization array and second statistics to estimate DOA -range parameter of near-field sources. The method has the merits of good estimate precision and no needing spectral peak searching. Its effectiveness is approved by the simulation results. |

| Keywords: | Near field source localization Polarization Bearing estimate Range estimate |
