| 摘 要： | 对宽带信号采用基于多项式聚焦矩阵的方法进行到达角估计，并进行了计算机仿真。计算机仿真表明，多项式聚焦矩阵具有计算量小、抗噪性好、能对相干信号进行到达角估计的优点，但需要满足阵元间距远小于信号半波长的条件。当阵元间距不满足该条件时，会引入较大的估计误差。

| Abstract: | The method of direction of arrival （DOA） estimation of wide-band signal by polynomial focuse-matrix and computer simulation was carried out. The simulation result showed that, the method of polynomial focuse- matrix had such excellence as less calculation, good noise immunity. And it could also be applied to DOA esti- mation of coherent wide-band signals. But the condition of that the array distance was far less than the signal＇ s half wave-length needed to be satisfied. If the condition of array distance was not satistied, it would produce estimation error. |
