【摘要】 声源被动定位的重要问题在于如何提高定位精度、定位速度和扩大定位范围。本文基于射线声学模型,利用声线最短传播时间在基元之间的时间延迟和多途时间延迟,提出了最短传播时间延迟定位、细分声场二次定位和多途时延定位及其他们之间相互结合的定位方法,使得定位精度得到明显提高,定位距离突破传统的匹配定位范围,实现了较高精度的远距离声源定位。理论研究的结果表明,该方法有效地降低了计算量,定位距离达到60 km,定位距离误差小于3%。更多还原

【Abstract】 The improvement of accuracy, processing speed and working range are key problems for passive source localization. Based on ray models, a new method of shortest travel time delay localization, detailing the sound field localization and multi-path time delay localization has been presented in the thesis. Using the method, source localization in long range has been realized. The results show that the accuracy of localization is greatly improved, the working range is up to 60km and its error is less than 3 percent.更多还原
