Abstract
In order to ensure the reliable,accurate and continuous reception of Beidou System(BDS)satellite signal under complex electromagnetic environment,a space-time joint anti-jamming technology by combining power inversion and minimum mean squared error criterion is proposed based on analyzing the theoretical model of anti-jamming and high-precision combined processing.This method can realize the anti-jamming processing of BDS signal and the phase response of carrier measurement without distortion under the conditions of BDS signal guidance vector acquisition failure,changing array manifold characteristic or the unknown signal incidence angle.Simulation results show that the carrier-phase distortion error of the proposed method is less than 1%of the whole-cycle when the jamming-noise-ratio reaches 50 dB,which can meet the requirements of anti-jamming and high-precision measurement and support a variety of tactical applications for precision approach guidance technology.关键词
