摘要：

针对宽带接收机对窄带信号进行频率和到达角估计问题，提出了一种新的快速频率和角度估计方法．首先利用参考频率进行到达角预估计，然后利用空域滤波有效地将频率和预估计到达角进行匹配，并根据天线阵列的结构特点利用信号的相应频率进行预估计到达角校准，获得了信号的准确频率和到达角估计值．仿真分析验证了所提出方法可实现宽带接收机的窄带信号到达角和频率的快速估计．

Abstract:

For the problem of the frequency and direction of arrive (DOA) united estimation of the narrow band signal for a wide band receiver, a novel quick method is proposed. First, the pre-estimation is used to get the pre-estimating DOA with the reference frequency, then the space filtering method is used to make the match of the signal pre-estimating DOA with its frequency, and the corresponding frequency is used to adjust the pre-estimating DOA according to the characteristic of the antenna configuration, so that, the precise signal frequency and its DOA are obtained at the same time. Simulation indicates that the proposed method is correct and effective for estimating the frequency and DOA of a narrow signal for a wide band receiver.

Key words: array signal processing, direction of arrive estimation, frequency estimation, wide-band receiver
