摘　　要：针对地基电磁频谱监测设备地域覆盖面积小、辐射源定位精度低等应用短板,提出了一种基于低轨微纳星座的星地联合电磁频谱监测技术,通过星间、星地的协同工作,能够以较低代价实现广域电磁频谱态势的连续、动态感知以及干扰源、非法用频终端等辐射源的快速、精确定位,经仿真分析,监测范围、定位精度相比地面监测设备实现了数量级的提升。最后,设计了15kg量级电磁频谱监测立方星方案,为军民融合推广应用奠定了技术基础。Ground electromagnetic spectrum detection has shortcomings in detection distance and radiation location accuracy.Micro-satellite based space-ground coordination electromagnetic spectrum detection technologies are proposed for large-area dynamic detection and quick radiation location application.According to the simulation results,micro-satellite based electromagnetic spectrum detection coverage area and radiation location accuracy are improved obviously,compared to ground electromagnetic spectrum detection.Finally,an electromagnetic spectrum detection cube-satellite is designed for civil-military integration application.
