In order to ensure that a satellite navigation receiver is able to work under the navigation warfare environment, a design for dual system anti-jamming satellite navigation receiver is proposed. Space-time anti-jamming technology is analyzed, which takes linearly constrained minimum variance (LCMV) as the optimal criterion, weighted by power inversion, enhanced anti-jamming capability of the receiver. Digital beam forming technology with a stronger anti-jamming performance is realized by feedback of satellite orientation information from baseband. Simulations show that traditional space-time interference suppression technology can realize 70dB anti-jamming capability for an interference, and by introduction of the beam forming technology, the anti-jamming capability for an interference can achieved 85dB.
