摘　　要：随着全球低轨星座系统蓬勃发展,不同星座系统卫星覆盖波束相互叠加,带来了频谱态势的复杂化,给其他系统带来了干扰隐患。传统的电磁频谱监视方案无法有效评估和高效表征低轨星座系统电磁辐射特性。为准确量化评估不同低轨星座卫星系统的电磁干扰,研究低轨星座卫星系统的电磁发射模型,结合轨道动力学研究电磁发射覆盖范围的动态分析方法,实现了低轨星座卫星电磁发射高效评估及可视化。With the global boom, Leo constellation system covering different satellite constellation system beam overlap, the spectrum of complicated situation, brings interference to other system hidden trouble of traditional electromagnetic spectrum monitoring scheme can’t effective assessment and efficient characterization of electromagnetic radiation characteristics of Leo constellation system for accurate quantitative evaluation of different Leo satellite constellation system electromagnetic interference, electromagnetic emission model of the Leo satellite constellation system, combined with orbital dynamics research cover the range of electromagnetic launch dynamic analysis method, has realized the Leo satellite constellation electromagnetic emission efficiency evaluation and visualization.

关 键 词：动态辐射源 电磁干扰 轨道动力学 可视化评估
