Abstract

The embodiment of the invention provides a deception interference source positioning method, electronic equipment and a storage medium, and the method comprises the steps: screening out a plurality of receiving terminals from a plurality of receivers in a target interference region, and obtaining the receiving signal information and position information of the plurality of receiving terminals; adopting a corresponding interference source positioning algorithm according to the number of interference sources, and employing the interference source positioning algorithm to determine the positions of the interference sources according to the received signal information and the position information; setting a verification terminal, determining an expected interference power at the position of the interference source by using the verification terminal, obtaining an estimated interference power at the position of the interference source, and comparing the expected interference power with the estimated interference power to determine whether a deception interference attack exists in the target interference area; and if the deception jamming attack exists, reporting the position of the interference source in the target area.

Description

Technical field

[0001] One or more embodiments of the present specification relate to communication security technology, in particular, to a spoofing interference source positioning method, electronic device, and storage medium. Background technique

[0002] Global Navigation Satellite System (GNSS) The receiver can provide positioning, navigation, and timed services, have become indispensable tools in everyday life, widely used in military equipment and in daily life. For security, reliability requirements, trustworthiness timing is particularly important. In the GNSS system, the satellite signals are very weak due to the ground, which is very susceptible to interference, including crimped interference and deceptive interference. Where deceased interference can destroy even control timing positioning results without noticeable, deceived interference is more threatened than suppressed interference. Especially with the development of electronic warfare technology and integrated ci...
