Abstract: According to the characteristic of navigation receiver in the missile, the anti-jamming model of high dynamic conditions is built. Taking into account the characteristic of interferences in high dynamic conditions and the shortcomings of traditional null widening methods, a novel Statistical Space Time Null Widening (SSTNW) method is proposed. The proposed method can suppress interferences effectively in high dynamic conditions and interferences position disturbed by non-ideal factors, i.e., it may improve the robustness of anti-jamming algorithm of navigation receiver in the missile remarkably. Simulation results show the feasibleness and effectiveness of the proposed method. -
