Communication satellite frequency spectrum monitoring equipment and frequency spectrum acquisition and feature identification method thereof

Abstract

The invention discloses communication satellite frequency spectrum monitoring equipment and a frequency spectrum acquisition and feature identification method thereof, and belongs to the technical field of satellite communication and frequency spectrum monitoring. The equipment realizes long-term monitoring of GEO communication satellite signals, acquires and automatically stores each satellite signal spectrogram in real time, completes statistical analysis of resource utilization and carrier distribution related to each satellite signal, and provides a basis for resource scheduling and network optimization of a satellite communication system; effective identification of satellite carrier signal parameters is realized, legality inspection of carrier signals is completed, an alarm is givenin time when abnormity is found, and support is provided for autonomous operation and troubleshooting of the system; and interference monitoring of satellite signals is realized, accurate identification and automatic alarm of interference parameters are completed, and a reference is provided for anti-interference decision making of the system. Two paths of satellite downlink signals within the frequency range of 70-6000MHz can be received at the same time, and the functions of frequency spectrum generation, parameter identification, interference monitoring and the like are completed on the received signals.

Description

technical field [0001] The invention belongs to the technical field of satellite communication and spectrum monitoring, in particular to equipment suitable for the scene of GEO communication satellite spectrum monitoring. Background technique [0002] In today's communication environment, especially in the satellite communication environment, it is very important to monitor the satellite signal in real time to obtain the spectrum pattern and signal parameters of the satellite transponder, so as to analyze the working status of the satellite transponder, judge whether there is interference, and grasp the current available resources of the communication satellite. . [0003] Existing solutions mainly rely on spectrum analyzers to obtain the spectrum pattern and signal parameters of satellite transponders. Its real-time performance is difficult to meet the needs of some special application scenarios, and it is impossible to complete automatic detection and alarm of interference...

Problems solved by technology

[0003] Existing solutions mainly rely on spectrum analyzers to obtain the spectrum pattern and signal parameters of satellite transponders. Its real-time performance is difficult to meet the needs of some special application scenarios, and it is impossible to complete automatic detection and alarm of interference. It also affects the utilization of transponder resources. Long-term real-time statistics cannot be achieved, and more rely on users to conduct secondary analysis and judgment

And the equipment is relatively bulky and the cost is relatively high
