Problems solved by technology

However, with the increasingly dense orbital positions, the wide-ranging use of different frequency bands, and the increasing utilization of transponders year by year, the dual-star positioning technology is becoming more and more limited, that is, whether there are qualified neighboring stars to achieve dual-star positioning Technology has become one of the major bottlenecks to successful pinpointing
Due to the influence of parameters such as satellite orbit position, frequency band, polarization, transmitting antenna aperture, and coverage, it is often impossible to perform positioning based on dual-star positioning technology, or it cannot meet the aforementioned dual-star positioning conditions, so a new positioning technology is needed. To solve the above interference positioning problem

Abstract

The embodiment of the invention provides a method and system for positioning an interference source based on a single stationary orbit satellite. The system comprises a signal collecting device, a reference source signal emission device, a signal processing device and an interference source positioning device, wherein the signal collecting device is used for collecting an interference signal of the stationary orbit satellite, the reference source signal emission device is used for sending a reference source signal to the stationary orbit satellite, and receiving a reference source return signal sent by the stationary orbit satellite according to the reference source signal, the signal processing device is used for conducting error removal on actual Doppler frequency shift of the interference signal and the reference source return signal, and the interference source positioning device is used for determining the position of the interference source according to the interference signal and the reference source return signal. Accurate positioning on the interference source of the satellite can be achieved through the only one stationary orbit satellite, the finding capability of the satellite on the interference is greatly improved, and a plurality of restraint conditions of interference finding are reduced.

Description

technical field [0001] The present invention relates to radio technology, especially to the field of geostationary satellite communication, specifically a method and system for locating interference sources based on a single geostationary orbit satellite. Background technique [0002] With the development of wireless communication technology, people's demand for spectrum resources is increasing, and the phenomenon of "spectrum exhaustion" is becoming more and more obvious. In the field of geostationary satellite communication, radio interference incidents caused by factors such as spectrum shortage will inevitably appear. Communication satellites are increasingly interfered by ground transmission sources. A huge threat is coming, and it may even have immeasurable social impact. [0003] In order to deal with these radio frequency interferences, it is very necessary to quickly and effectively determine the location of ground interference sources through the interfered satell...
