A Repeater Deception Jamming System Based on High Gain Antenna Array Spatial Separation Receiving

Aiming at the problems of high cost and high-power consumption of the existing repeater satellite navigation deception jamming system, a repeater deception jamming system based on high gain antenna array spatial separation reception is designed. Through eight sets of high-gain parabolic antennas, the appropriate satellite is selected to obtain a single satellite signal, and then the time delay of each satellite signal is accurately controlled according to the spoofing position point, and the pseudo-range information is changed. Finally, the target receiver is transmitted to the target receiver in a combined way to achieve the purpose of deception. At the same time, in order to ensure the effectiveness of the interference, combined with the satellite space geometry, the optimal satellite strategy algorithm is designed. Field experiments show that the system can successfully deceive typical receivers.
