Research on localization principle and method for multistation range-only target tracking system

Abstract

Observable condition for multistation range-only system was analyzed according to the characteristics of underwater target localization in the conditions of network warfare. When the target is stationary or travels in straight-line movement, it is able to be observed by range-only system. The target localization parameters are estimated by least squares estimator algorithm, which has simple form and does not need initial values. Simulation results show that the algorithm has fast convergence speed, good stability and high accuracy.
