摘　　要：以机载雷达和干扰机为例,分析了机载设备电磁兼容问题产生的原因,建立了电磁相互干扰的理论模型,探讨了载机在不同干扰方式下雷达作用距离计算方法,推导了互干扰时,载机在掩护式干扰和自卫式干扰两种情形下的雷达距离方程,并基于雷达检测概率的一般求解方法,推导了自卫式干扰时雷达检测概率与目标距离的关系,并进行了实例仿真,为解决互干扰问题提供了理论参考。Using the example of airborne radar and jammer,the EMC cause of airborne devices is analyzed and theory model of electromagnetic mutual jam is established.Under the different jamming circumstance and modes,a calculate measurement of airborne radar detection range is put forward and radar range equation in jamming condition is developed when blanketing jamming and self-protection jamming occur.On the basis of common calculate measurement of radar detection probability,the relation between radar detection probability and target distance is deduced in self-protection jamming and simulations are accomplished.It is a reference for solving.
