Abstract: A tracking method with velocity measurement is proposed to improve the performance of passive target tracking of multi-observation stations. The angular velocity measurements are presented in the nonlinear forms of target's position and velocity in Cartesian coordinate. The tracking performance of passive target tracking system after using angular velocity measurement is analyzed with Cramer-Rao lower bound.An implement process of passive target tacking is presented based on unscented Kalman filtering method. Simulated and experimental results show that the passive target tracking system with angular velocity measurement improves the estimation accuracy of target motion parameters. Key

Key words: passivetargettracking, angularvelocity, nonlinearfiltering, Cramer-Raolowerbound
