Given that Bearing-Only the location algorithm is time-consuming, not strictly accurate and can-not work in real-time when facing targets at a constant speed along a straight line in two dimension. So this paper proposes a combined radiation target Doppler frequency information and adopts the square root central difference Kalman Filter (SRCDKF) algorithm in a bid to achieve effective tracking and positioning of the system. The simulation results show that the proposed algorithm in the system model solves the problem that extended Kalman filter (EKF) and Particle Filter (PF) algorithms can-not converge and performs well in filtering accuracy, convergence, and stability.
