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.
