摘　　要：自适应调零抗干扰技术能够很大程度改善卫星导航接收机的抗干扰能力,被广泛运用于精确制导武器中,是当前卫星导航对抗问题研究的重点。针对多阵元自适应调零接收机,分别模拟了不同数目干扰源,以及干扰源在入射方位角和俯仰角不同条件下的干扰效果,分析得到接收机抗干扰能力量化值,并提出针对性的对抗方法。结合实验结果和数据得出结论,发现通过调整干扰源数量、以及设置角度,可以有效抑制接收机的抗干扰能力的发挥,从而实现对干扰资源的合理配置,以上结论对进一步研究干扰源布设的优化方法具有较强的实践指导意义。Adaptive nulling anti-jamming technology can greatly improve the anti-jamming ability of satellite navigation receiver.It is widely used in precision guided weapons.It is the focus of current research on satellite navigation counter-measure.This paper simulates the anti-jamming performance of multi-element adaptive nulling receiver in the face of jamming sources with different numbers,different incident azimuth angles and different incident pitch angles,quantitatively analyzes the improvement of the anti-jamming ability of the receiver,and puts forward targeted counter-measure schemes.Based on the experimental results and data,it is found that by adjusting the number of interference sources and the setting angle,the anti-jamming ability of the receiver can be effectively suppressed,so as to achieve a reasonable allocation of jamming resources.The conclusion has a strong practical guiding significance for the further study of the optimization strategy of jamming source deployment.
