基于检测前跟踪的声源跟踪算法
Acoustic source tracking algorithm using track before detect
摘要
Abstract
In order to improve tracking performance in a noisy and reverberant environment,an acoustic source tracking algorithm using track before detect was proposed. This algorithm used a modified steered response power as localization function which take into account a rectangular region to achieve more robust source location estimation than steered re-sponse power function and applied track-before-detect technology to avoid reduplicate calculation of the same rectangu-lar region so that the algorithm could reduce the computation burden without decreasing the accuracy. The simulation re-sults verified that the proposed algorithm can achieve more accurate tracking results than traditional tracking algorithm in a noisy and reverberant environment.关键词
