Abstract

The invention relates to an unmanned plane communication interference countermeasure method based on a real-time embedded control system and belongs to the technical field of unmanned plane communication countermeasure. The method comprises steps of: S1, constructing an unmanned plane antenna model; S2: analyzing the characteristic of the antenna by using a time-domain finite difference method; S3, acquiring the field distribution of the antenna fixed in a coordinate system on a spherical surface at a certain distance in a far area; S4, transforming an acquired value into field distribution of the antenna in any attitude by using transformation of coordinates; S5, transforming the field distribution on the spherical surface into ground in order to obtain a relation between ground coordinates and effective interference power; and S6, adjusting the flying attitude of an unmanned plane in order to perform ground communication interference. The method may effectively and accurately adjust the flying attitude of the unmanned plane in order to maximize the interference effect of the unmanned plane on a ground communication system and effectively prevent defects of conventional ground communication countermeasure, and has high application value in the field of unmanned plane communication countermeasure.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle communication interference countermeasure method based on a real-time embedded control system, and belongs to the technical field of unmanned aerial vehicle communication countermeasures. Background technique [0002] Communication countermeasures are an important part of electronic countermeasures. Radio communication interference is an interference measure taken against the radio communication of the other party. Because the medium of radio communication - electromagnetic wave has a characteristic: when two or more electromagnetic waves of the same frequency work together, the receiving device will receive the superposition of these two or more signals, thus making the received signal blurred. Utilizing this characteristic of electromagnetic waves, radio interference equipment can transmit interference signals with the same frequency as the electronic signal of the other party, which can cause the ...
