基于四阶累积量的DOA估计方法及其分析

Estimation and Analysis of DOA Based on Fourth-Order Cumulant

本文提出了一种基于四阶累积量的DOA估计方法，同MUSIC-like方法一样，它也对实际阵列进行了四阶扩展文章证明了这两种方法对实际阵列口径和阵元数的扩展特性，指出了它们在阵列扩展方面的差别文章最后采用计算机模拟验证文中结论．

In this paper, a fourth-order cumulant-based estimation method is presental. As the MUSIG-like method,the method can extend the red array to a virtual extensive array. Especially the paper analyses the characterizations of the two extensive arrays in detail. The relative conclusions are got and verified by the simulation experiments.
