| 摘 要： | 时频分析已经应用到了许多领域 ,Forrester,Atlas et al.和 Williams最先认识到时频分析在机器故障检测这一领域的重要性 ,并且做了大量的研究工作。在生物和生物医学中 ,时频分析的应用也很广泛。在通信领域 ,A m in也把时频分析作为一种有效的工具来使用。当然 ,时频分析在信号检测与信号分类中也得到了广泛的应用。近来 Am in将时频分析应用到统计信号处理和阵列信号处理之中 ,取得了很多重要的进展。本文主要综述时频分析在阵列信号处理中的应用。时频分析在阵列信号处理中主要有两方面的应用 ,一是时频 MUSIC,一是空时频分布

| Abstract: | The method of timefrequency analysis has been used in many different fields Forrester, Atlas et al and Williams developed its applications in the field of failure testing of machines It has been great developed in the field of biology and biomedicine In the field of communication, Amin referred the method as an effective tool to deal with statistical signal processing and array signal processing and have made great progresses This article will pay attention to the application in the field of array signal processing There are two aspects in the application of the timefrequency method in the field of array signal processing One is timefrequency MUSIC,the other is space time frequency distribution |
| |
| Keywords: | array signal processing time-frequency MUSIC spacial time-frequency distribution spacial average |
