摘　　要：论文根据弹载导航接收机的特点,建立了高动态环境的抗干扰模型;针对高动态环境下干扰的特点和传统零陷加宽方法的不足,提出新的基于统计的空时零陷加宽方法。该方法能在高动态条件和其它非理想因素引起的通道及数据失配的情况下有效地抑制干扰,大大增强弹载导航接收机抗干扰算法的鲁棒性。仿真试验表明了所提方法的有效性。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.
