摘要

提出了一种针对均匀圆阵接收信号波达方向(direction of arrival，DOA)判定的算法，该算法相对于其他算法，更能充分利用信号中的有用信息，达到提高算法判定精度的目的.算法将接收信号数学模型在

轴和

轴方向分别进行虚拟平移，通过模式激励，构造出两个包含接收信号DOA信息的满秩Toeplitz矩阵，达到相干信号解相干的目的.先后根据

轴、

轴方向旋转因子特性的不同，先得出信号俯仰角的估计值，再得出方位角的估计值，完成二维波达方向的判定.仿真结果验证了该算法对于相干信号DOA判定的正确性，而且对于强相干和低信噪比的入射信号DOA也能有效区分和判定.

Abstract

A new algorithm aiming at improving the estimation accuracy of direction of arrival (DOA) based on uniform circular array (UCA) has been proposed in this paper. Compared with other algorithms

the new proposed one can make the most of the useful information hiding in the received signal by shifting virtually in two vertical direction. Firstly

it shifts the mathematical mode of array received signals at the

axis and

axis respectively with the method of mode excitation. And then

two new full rank Toeplitz matrices relating to the information of DOA estimation have been reconstructed so the purpose of decorrelation has been achieved. Through the different properties of rotation factor at

axis and

axis successively

the researchers obt

ain the estimation of pitch angle and then the estimation of azimuth angle. Result analysis of simulation shows the validity of the DOA estimation of coherent signal as well as the strong coherence and low SNR incoming signals.
