基于柔性阵自修正的水下移动网络定位机制
Underwater mobile network localization mechanism based on self-correction of flexible arrays
摘要
Abstract
Aiming at the problems of large communication and time overhead in formation keeping,and low passive localization accuracy due to difficulties in underdriving and arrays determination in existing underwater unmanned platforms,an underwater mobile network localization mechanism based on self-correction of flexible arrays was proposed.Through a low overhead fast array determination and localization protocol and a quasi-real-time self-correction strategy,the mechanism effectively reduces the localization error of the base array.Meanwhile,in order to address the complex water medium environment,an error compensation mechanism for the sound speed stratification effect was introduced,and the target position was solved based on the spherical interpolation method to realize the passive localization of the target by mobile network under weak communication conditions.Simulation and sea trial results show that the proposed method has better stability and higher accuracy than existing methods.关键词
