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.
