摘要
Abstract
Maximum Likelihood Estimation is widely used in the multiple-source localization based on acoustic energy in wireless sensor networks; but it ignores the interaction effect of the targets' energy. This article used Independent Component Analysis to obtain the interaction effect of the targets' energy, established acoustic energy model on this basis, and at last estimated the targets' location using maximum likelihood method. The experiment result proves that this method delivers more accurate results and better anti-noise ability than the existing maximum likelihood multiple-source localization method.关键词
