中文摘要:
      提出一种基于共享数据库技术的空间电磁环境监测系统方案,设计机载现场可编程门阵列(FPGA)核心频谱采集分析模块,开发信号传输链路、数据处理及系统显示控制软件。基于共享数据库技术,利用无人机(UAV)机载信号采集模块,将测量到的空间频谱数据和地理位置信息实时回传;终端显示控制系统将监测数据分别以频谱图和辐射热图的方式,在数字地图上对所测空间区域电磁频谱分布实时直观显示,将电磁频谱监测从地面扩展到三维空间。试验证明,本系统可高效灵活地监测空间频谱的实时变化情况,为频谱管理、空间电磁环境实时监测以及发射源侦测定位提供重要的技术支撑。
英文摘要:
      A method for monitor system of electromagnetic environment in spatial based on shared database is proposed. Acquisition and analysis module that install on Unmanned Aerial Vehicle(UAV) for spectral information is designed and the control software for signal transmission, data processing and system display is developed. Based on shared database technology, the spatial electromagnetic data and GPS information are received in real time, which are acquired by signal acquisition and analysis module installed on UAV, and then, in real time, the terminal control system displays these information on digital map in the form of spectrogram or radiation heat map, all of which extend electromagnetic spectrum monitoring from the ground to three dimensional space. Finally, experiment and measurement show that the system can efficiently and flexibly monitor the real-time change of space spectrum, and provide important technical support for spectrum management, real-time monitoring of spatial electromagnetic environment and detection and localization of emission source.
