摘要

In this article, a direction of arrival (DOA) based estimation method is proposed for the localization of acoustic gas leakage sources indoors, with the use of a microphone array. Since the narrowband signal assumption for the uniform circular array (UCA)-MUSIC and ESPRIT methods are not applicable to the case of gas leakage sources, different approaches including the incoherent, coherent, and fre...
