Abstract

Abstract

In case of the traditional three-satellite time-frequency difference positioning system with unknown elevation, it will produce positioning errors caused by the target speed to the moving state radiation source. A new method of fusion passive tracking is proposed, which uses the Direction Of Arrival (DOA) information of the main star and combines the Time Difference Of Arrival (TDOA) and Frequency Difference Of Arrival (FDOA) information of the three satellites. First, a positioning model is established on the basis of coordinate system transformation, and on this basis, an improved Iterative Extended Kalman Filter (IEKF) algorithm is used to track moving objects of unknown elevation. The simulation results of the algorithm show that this method can realize the positioning, tracking and speed measurement of the moving radiation source without knowing the height information of the target, and the position and speed estimation of the target are improved.
