Path Planning For Single Motive Station Using TDOA Localization
摘要
Abstract
When conducting underwater targets positioning by a single platform using Time Difference of Arrival(TDOA),the path of the platform has a significant impact on positioning accuracy.To address the problem of how to plan the path and improve localization precision,a single-platform path planning method based on an improved dynamic window approach(DWA)is proposed.In the evaluation function of the conventional DWA algorithm,a localization precision evaluation sub-function is introduced,which is designed to minimize the horizontal dilution of precision(HDOP).Considering that the weights of the heading angle and localization precision evaluation sub-functions are related to the distance from the observation platform to the target,the weight coefficients of the heading angle and localization precision evaluation sub-functions are also optimized to allow for dynamic adjustments.Simulation results show that the path planned by the improved DWA algorithm can avoid obstacles while improving localization precision.关键词
