Abstract :
In order to solve the problem of satellite moving interference location, a localization algorithm based on search optimization for dual satellite systems is presented. By using the measurements of the TDOA/FDOA and the Doppler frequency of the moving interfering transmitter, the position of the moving interference can be located in the point of intersection of the curved surface of TDOA/FDOA and the Doppler frequency theoretically. Simulation results verify the effectiveness of the proposed algorithm.
