System and device for monitoring and recording frequency spectrum of satellite radio frequency channel

Abstract

The invention provides a satellite radio frequency channel spectrum monitoring and recording system and device. The satellite radio frequency channel spectrum monitoring and recording system comprises a main control module, an instrument driving control module, a real-time display and control module, a waterfall plot display module, a 3D plot display module, a normal monitoring module, a storage module and a playback module. The main control module is respectively connected with the instrument driving control module, the real-time display and control module, the waterfall plot display module, the 3D plot display module, the frequent monitoring module, the storage module and the playback module, the instrument driving control module is connected with the spectrum analyzer, and the storage module is connected with the playback module. Any time period of the monitoring data can be positioned through the frequency spectrum data, and postmortem analysis and processing of abnormal data are facilitated; long-time spectrum data peak value or in-band energy display can be realized, and spectrum trend change or abnormity can be conveniently explored; a text and sound alarm mode is used to remind a user that the spectrum is abnormal in real time, so that the user can respond and process quickly.

Description

technical field [0001] The present invention relates to a spectrum monitoring and recording system, in particular to a satellite radio frequency channel spectrum monitoring and recording system, especially a satellite radio frequency channel spectrum monitoring and recording system and device of Fengyun satellite ground application system. Background technique [0002] Fengyun meteorological satellites play an important role in disaster prevention and mitigation in my country. The acquisition of remote sensing data is transmitted to the ground application system through the satellite radio frequency channel. The quality of the radio frequency channel directly affects the transmission of satellite telemetry data and payload data. Therefore, it is very necessary to monitor and record the spectrum of the satellite radio frequency channel. At the same time, the spectrum out-of-tolerance alarm can effectively improve the effectiveness of satellite abnormal state processing and eff...
