Abstract:

As an important technology of electronic reconnaissance in modern information battlefield, passive positioning technology can achieve accurate localization without emitting radio waves. Taking the unmanned aerial vehicle (UAV) cluster with high flexibility and security as receivers, this paper studies the localization method of emitter target based on time difference of arrival (TDOA) measurement. As a high maneuvering platform, UAV cluster has higher station location error, the improved algorithms of Chan algorithm and Taylor algorithm are simulated under this situation, and a new algorithm based on Taylor particle swarm cooperation is also proposed. Compared with other methods, the simulation results show that the positioning accuracy of the proposed method is close to the Cramer-Rao lower bound (CRLB), and solves the initial value problem of Taylor algorithm.

Key words: passive positioning, time difference of arrival (TDOA), particle swarm optimization (PSO)-Taylor algorithm, single target location
