GPS Anti-jamming Performance Simulation Based on LCMV Algorithm

Abstract

The most efficient and effective adaptive control of the GPS anti-jamming technology is the adaptive zero adjusting antenna. Aiming at anti-jamming problem of GPS receiver under interference condition, the LCMV algorithm is used to simulate and analyze the number of different interference sources and different dry to noise ratio in uniform linear array. The results show that the method can suppress the interference signal effectively, and can realize the high gain reception of the desired signal direction, and the higher the interference the better signal power. Finally, using satellite ephemeris and inertial navigation parameters, to calculate the satellite signal solution of antenna array of DOA, then the LCMV algorithm is proposed in this paper can form the main beam to the desired signal to receive the desired signal on high gain.
