Abstract:
A satellite navigation receiver that can suppress jamming interference and spoofing interference simultaneously is designed in this paper.An anti-jamming improved constrained spacial adaptive processing algorithm in signal processing and an anti-spoofing M-estimator based extended Kalman filter algorithm in information processing are proposed respectively.Simulations of the integral designed anti-interferences satellite navigation receiver demonstrate that the designed anti-interferences receiver can suppress jamming signals efficiently (above 40 dB) and ensure the normal reception of satellite signals while satellite signals and jamming signals have the similar direction of arrival (almost 10°).The designed anti-interference receiver can effectively eliminate the influence of spoofing signals on the navigation solution accuracy and maintain high accuracy of position and velocity estimation,which improves the anti-jamming and anti-spoofing capability of the satellite navigation receiver.
Key words: anti-jamming anti-spoofing satellite navigation receiver
