| 摘 要： | 提出了一种基于子空间2次旋转变换的频率-方向联合估计方法．该方法可同时估计空间信号频率和到达方向，其阵列由M个阵元组成，避免了复杂的阵列结构．计算机模拟结果表明，该方法不仅阵列结构简单，在中等SNR时具有良好的分辨性能，而且运算速度较快。

| Abstract: | A new approach to jointly estimate spatial signal frequencies and directions of arrival (DOA) based on bi-rotation signal subspace is proposed. The two rotation matrixes are derived to transform signal subspace and obtain new subspaces. With this method the frequencies and DOA can be estimated simultaneously. A simple array structure consists of M sensors. In middle SNR, computer simulation shows the approach has good performances in resolution and speed. |
