信号检测和估计 - First , the definition and properties of hos are introduced . we especially notice that hos is insensitive to gaussian process . this is the theoretical basis of signal detection and estimation
文章首先介绍了高阶统计量的定义和性质，特别指出了高阶统计量对高斯过程不敏感，这是我们利用它进行信号检测和估计的理论依据。 - They are almost based on the theory of conventional detection and estimation . so when the signal to noise ratios of the received signals becomes lower , the performance of these methods take a turn for the worse , and these methods don ’ t work
这些方法大多基于常规信号检测和估计理论,对于宽带微弱的ds信号,当信噪比较低时,这些估计方法的估计性能急剧恶化,不能得到有效的估计结果。 - The techniques of low probability of intercept ( lpt ) are developing rapidly , and are used widely in radar and communication . in order to counteract the lpi techniques , there is necessary to research the new methods of detection and estimation of lpi signals
目前低截获概率( lpi )技术发展迅速，并在雷达和通信中获得广泛应用，为对抗这些技术带来的检测和估计问题，需要研究低截获概率信号检测和估计的新方法。 - The study of ds signals in this article broke through the conventional detection and estimation methods and modeled the ds signals as a cyclostationary random process . in this case , it can be analyzed by the theory of spectral correlation , and then we can finish the parameter estimation of ds signals by its characteristic in the field of spectral correlation
本文对低信噪比下的ds信号的研究突破常规信号检测和估计理论,将ds信号建模为周期平稳随机过程,应用谱相关理论来分析它的谱相关域特性,寻求ds信号的参数在谱相关域的特征表现,从中提取相应的ds信号参数信息。
