摘　　要：给出了基于MUSIC方法估计海洋表面径向流方位 (DOA)时 ,高频地波雷达角分辨率的定义、误差及其估计方法。讨论了海洋回波信噪比、样本数、阵元数等因素对海流角分辨率的影响 ,根据实际情况对上述影响进行了模拟 。As continuous target, ocean wave surface current is different from hard target. Thus, its angle resolution should be re-defined as well as resolution error and estimation method. We applied MUSIC algorithm to study DOA of current obtained by HF ground wave radar. Several major facts affecting angle resolution are discussed, such as SNR, sample number and antenna element number. All these infections are taken into account in simulation experiment. The result confirms that angle resolution achieves prospective goal.
