用于声线跟踪定位的自适应分层方法
A self-adapting division method for ray-tracing positioning
摘要
Abstract
Ray-tracing technology is an indispensable method to effectively handle the problems associated with sound-trail bends and helps promote the positioning performance of the high -precision acoustic positioning system .It is difficult to solve the conflict between the positioning precision and the amount of computation for the equal -interval division problem which is widely used in practice .In this paper , a self-adapting division method based on the equiva-lent sound velocity profile theory is presented .By controlling the interceptive error of sound velocity , the division re-sults of this method is optimized to have the least amount of layers and unequal intervals , and its performance is ana-lyzed.The experiments show that compared to the equal-interval division , 70%of the computation is economized by using the self-adapting division method to locate a 5 000 m target for the same precision .关键词
