摘　　要：安防监控铁塔是一种复杂的电磁散射体目标,为了解安防监控铁塔的RCS特性对周边环境的影响程度,对安防监控铁塔进行建模分析、CAE建模、电磁仿真等。通过仿真计算得出了安防铁塔在X、Ku、Ka三种频段下的RCS空间分布情况。仿真结果表明,对安防监控铁塔在擦地角0°~90°范围内的点频RCS进行概率值和均值统计,大部分情况下RCS都比附近某大型物体RCS低10 dB以上,电磁影响有限。The security monitoring tower is a complex electromagnetic scattering target.In order to understand the impact of the RCS characteristics of the security monitoring tower on the surrounding environment,modeling analysis,CAE modeling,electromagnetic simulation,etc.are carried out on the security monitoring tower.Through simulation calculations,the spatial distribution of RCS of the security tower in the X,Ku,and Ka frequency bands is obtained.The simulation results show that the probability and mean statistics of the point frequency RCS of the security monitoring tower within the range of 0°~90° ground clearance angle show that in most cases,the RCS is more than 10 dB lower than that of a nearby large object,and the electromagnetic influence is limited.
