An Effective Single Passive Location Method Based on Near Space Vehicle for Ground Fixed Emitter
Fu Lai Liu, Hui Jia · Applied Mechanics and Materials · 2014
Ground target position estimation of near space vehicle is the key technology in military and civilian field. In this paper, we propose an effective method using the cubature Kalman filter (CKF) based on direction of arrival (DOA) and its rate of change. Comparisons with the location method only using DOA and the classic EKF algorithm are conducted respectively. Simulation results indicate that the proposed method has faster convergence speed and better location precision.
