| 摘 要： | 提出一种新的基于训练序列波达估计算法．新算法基于如下假设：各个信号源的训练序列互相正交；并且各个信号源都是幅度为1的恒模信号．论文给出了新算法的数学推导过程，得到一个简单的估计公式．结合无空间模糊性的T形阵列，新算法能够快速、精确地估计波达方向．

| Abstract: | A new method of estimating DOA based on training signal is proposed. The training signals of users are supposed to be mutually orthogonal and the magnitude of each signal is constant, that is 1. The mathematical deduction of the new algorithm leads to a simple estimating formula. Combined with T-shape antenna array , the new algorithm can estimate the DOA accurately and rapidly. |

| Keywords: | antenna array estimation of DOA array signal blind separation of signal sources |
