Simulation Research of High-living Spectrum Display in Space Electromagnetic Monitoring

XU Kan;WANG Tiancheng;Shanghai Institute of Satellite Engineering;  
In view of the cognition requirements of electromagnetic monitoring operators for various signal spectrums,this paper puts forward a low-cost and high-living implement scheme of virtual signal spectrum generating and display.This scheme can obtain the virtual signal spectrum of specified observation frequency range by calculating the receiving signal power on a normal PC and combining the signal spectrum characters with different modulation patterns without signal source and spectrum analyzer,and then the virtual signal spectrum is rendered to the screen by the video-card.The operating functions of a real spectrum analyzer such as VBW,RBW,PeakSearch,reference level are implemented in this scheme.The operator can select different signal spectrums by using different press keys.This paper gives signal spectrum display and spectrum operation examples,and the results show that this scheme has good training effects for monitoring operators who have not professional knowledge.
