摘要

本文分析了超宽带(UWB)阵列在空时域的特性，提出了一种脉冲信号到达方向(DOA)估计方法。该方法借鉴了通信系统中信号周期平稳的特点。通过对超宽带阵列输出信号的相关矩阵进行分解，得到超宽带阵列的DOA信息。仿真结果表明，在周期频率不高的情况下，该方法是有效的。

DOA estimation of ultra-wide band array antenna

In this paper, the characteristic of ultra-wideband (UWB) arrays is analyzed in space-time domain and a method of direction-of-arrival (DOA) estimation for impulse signal is introduced. This method borrows ideas from signal's cycle stationary characteristic in communication system. By decomposing the output signals' correlation matrix of the UWB arrays, the DOA information is obtained. Simulation result shows that if the cycle frequency isn't high, this method is valid.
