摘要
当前对于声源定位技术的研究非常火热,它主要由声学、信号接收、软件设计以及数字信号处理等学科组成,通常在研究声源定位时我们采用传声器阵列定位技术。而时延估计是传声器阵列进行信号处理的一项非常重要的技术,它的目的是对同源信号到达不同的传声器由于传输距离的不同而产生的时间差。现在,声源定位技术已经被广泛的应用到移动通信、智能探测等领域中。本论文对声源定位技术的发展现状进行了介绍,同时对时延估计的定位算法进行了相关介绍,最后得出声源定位未来将会被应用的更加广泛的结论。
at present,the research of sound source location technology is very hot.It is mainly composed of acoustics,signal reception,software design,digital signal processing and other disciplines.Usually we use microphone array location technology in the research of sound source location.Time delay estimation is a very important technology in microphone array signal processing.Its purpose is to get the time difference between the same source signal and different microphone due to the different transmission distance.Now,sound source location technology has been widely used in mobile communication,intelligent detection and other fields.In this paper,the development of sound source location technology is introduced.At the same time,the algorithm of time delay estimation is introduced.Finally,the conclusion that sound source location will be applied more widely in the future is drawn.
