摘要 基于二维DOA估计模型 ,本文研究了复杂环境———乘法与加法观测噪声共存时的DOA估计问题 .针对工程实践中广泛存在的循环平稳信号 ,提出了一种采用循环统计量的新方法 .该方法对任何平稳的加性与乘性噪声均不敏感 ,因而具有较大的实用性 . Based on the 2 D model,the case of DOA estimation in presence of complicated noise is studied in this paper.Focusing on the cyclostationary signal,widely existed in practice,a new method using cyclic statistics is proposed.It is the insensitivity to any stationary additive and multiplicative noise that makes it more practical.
