摘要

在分布式目标波达方向估计问题中

空间信号分布函数一般具有共轭对称性.本文提出了一种新的盲波束形成方法

不用进行多维参数搜索

不要求已知空间信号分布的具体函数形式

并适用于分布函数形式不同的分布式目标同时存在的情况.仿真实验结果表明

这种方法的波达方向估计性能对信号源的分布特性不敏感.

Abstract

By using a new blind beamforming method proposed in this paper rather than resorting to multidimensional spectra searching

we get an algorithm for DOA estimation of distributed signals.It needs little prior knowledge about the distribution function of the source and can be applied in nonuniform array condition.The simulation studies show that the new method outperforms conventional MUSIC algorithm by reducing the sensitivity for scenarios with distributed sources.
