| 摘 要： | 本文研究阵列信号高分辨波达方向-多普勒频率二维估计问题,在未精确已知阵列流形条件下,利用到达波信号的多普勒频率,提出了一种波达方向-多普勒频率盲估计的新方法。理论分析和计算机仿真结果表明此方法在实际阵列存在增益和相位误差时亦有效,而且与现有二维估计算法相比,其运算量较小。

| Abstract: | A novel blind estimate of direction of arrival (DOA) and Doppler frequency with unknown array manifold is proposed, employing Doppler frequency difference between a successive pulses as rotational parameter. The effectiveness of the new method is confirmed by computer simulations. Compared with the existing two-dimensional frequency estimates, the computation load of the proposed method can be saved greatly. |
