此基础之上提出了雷达最大作用距离衰减系数的概念，建立了最大作用距离衰减系数与天线
增益等六大参数的定量关系。最后，针对两部雷达间的干扰情况做了算例分析，仿真实验结

表明：降低天线副瓣增益、增加雷达间距离以及提高受扰雷达压制系数均可以获得较好的雷
达间电磁兼容性。这种将最大作用距离衰减系数用于雷达间电磁兼容判决的模型，能够真实

| Abstract: |
| In order to better judge radar electromagnetic compatibility(EMC), the effectiv
e
ness evaluation model of stand-off jammer(SOJ) is analyzed, the attenuation coef
ficient of maximum range is proposed based on SOJ evaluation model, the relation
ship between the attenuation coefficient and the six parameters(antenna gain,et
c
) of radar is established. Finally, interference of two radars is calculated, si
mulation results indicate that decreasing sidelobe gain, increasing the space be
tween of radars and improving the victim radar suppressing coefficient can achie
ve better radar EMC. This model which applies the attenuation coefficient of max
i
mum range to judge radar EMC can illuminate the interference condition between r
adars realistically and quantitatively. |
