Abstract

The invention discloses a method and a system for acquiring satellite carrier frequency domain distribution characteristic parameters. The invention relates to a method and a system for performing spectrum intensive inspection by using a low-cost digital spectrum front end and obtaining frequency domain distribution characteristic parameters of satellite carriers through analysis; high-speed spectrum inspection and carrier frequency domain distribution characteristic parameter analysis can be carried out on the full bandwidth of a satellite working frequency band, and the utilization rate of a spectrum front end is improved by utilizing input frequency band difference and a signal combiner, so the single-channel cost of the system is further reduced, and the problem that spectrum data splicing needs to be carried out due to the fact that the working bandwidth of the spectrum front end is smaller than the full bandwidth of the satellite working frequency band is solved.

Description

technical field [0001] The invention relates to a method and a system for obtaining characteristic parameters of satellite carrier frequency domain distribution, belonging to the technical field of satellite communication. Background technique [0002] For satellite resource managers who need to operate and manage satellite transponder resources, it is an important basic work to conduct spectrum inspection and obtain the characteristic parameters of the frequency domain distribution of satellite carriers. [0003] The existing satellite transponder spectrum monitoring system generally has two modes. One uses high-cost spectrum sampling equipment for spectrum monitoring and analysis. Due to the high price of spectrum sampling equipment, it is usually necessary to share the cost of each monitoring channel by switching the switch. The cost of spectrum sampling equipment and the complexity of the system usually need to be compatible with real-time operation and inspection requir...
