摘　　要：针对抗干扰导航接收机可抗多个不同来向干扰且抗单干扰能力强,单干扰源对抗干扰接收机的作用距离短,导致干扰效能低下的问题,提出一种面向抗干扰导航接收机的多源干扰优化部署方法:根据接收机的抗多源干扰的不同抗干扰容限,使多个干扰源在不同方向协同部署,形成多源协同干扰区域,从而更好发挥干扰源的干扰效能。仿真结果表明,所提优化部署方法最小干扰距离大于传统方法,有效干扰面积在文中不同参数下分别为均传统方法的9.08、112.64、1214.42倍,且相同参数下二者的干扰面积差随干扰功率线性增加,较传统的干扰源部署方法性能更优。Aiming at the problem that the anti-jamming navigation receiver can resist multiple different interference and has strong anti-single interference ability,and the single interference source anti-jamming receiver has short action range,resulting in low interference efficiency,the paper proposed a multi-source interference optimal deployment method for anti-jamming navigation receiver:according to the different anti-jamming tolerance of the receiver,multiple interference sources were deployed in different directions to form a multi-source cooperative interference area,so as to better perform the interference efficiency of the interference sources.Simulational result showed that the minimum interference distance of the proposed optimization deployment method would be larger than the that of the traditional method,and the effective interference area could be 9.08,112.64 and 1214.42 times of the traditional method under different parameters,respectively,moreover,the difference of interference area between the two methods would increase linearly with the interference power under the same parameters,indicating that the performance could be better than the traditional interference source deployment method.
