Abstract

The invention discloses a satellite communication frequency orbit resource data correction method based on joint probability, and the method comprises the following steps: firstly, carrying out the whitening processing of public data according to an equal-weight mean whitening method; then adopting a semi-supervised learning method, and utilizing declaration data and actual use data in the database to train a joint probability model; using the obtained joint probability model to correct whitening data; and performing inversion by using the corrected whitening data to obtain corrected data, and supplementing the database. The method mainly has the following advantages: a joint probability correction method is adopted, so that the data correction accuracy is high; a semi-supervised learning method is adopted, and the joint probability model is trained by combining public data and database data, so that the model is high in accuracy and simple to implement, and a large amount of manual annotation work is avoided; the satellite communication frequency orbit resource data correction algorithm is low in implementation complexity and can be conveniently and rapidly constructed.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a method for correcting satellite communication frequency orbit resource data based on joint probability. Background technique [0002] Space frequency track resources are non-renewable scarce strategic resources, and frequency track resources are very precious. At the current stage, with the development of the satellite industry in various countries around the world, many large satellites have been launched in space, occupying a large number of orbital resources, resulting in increasingly scarce available frequency orbital resources. Therefore, the efficient utilization of frequency track resources is of great significance. In the actual development of satellite communications, the mining of satellite frequency orbit resources is crucial to the efficient use of frequency orbit data, which can achieve the effect of making full use of frequency orbit resource data. However...
