Anti-interference communication system based on vortex electromagnetic waves

Abstract

At present, in anti-interference measures, when the signal capturing speed reaches the microsecond level and the interference equivalent radiation power reaches the megawatt level, a new-generation interference platform capable of realizing accurate suppression can be implemented, but a satisfactory effect can be difficult to obtain. The invention provides an anti-interference communication systembased on vortex electromagnetic waves. Interference signals in current communication countermeasure are common plane electromagnetic waves; all OAM modes of the interference signals belong to 0 modes; by adopting a vortex electromagnetic communication technology, electromagnetic signals of which OAMs are not zero are generated for performing information transmission; and based on the orthogonality between different modes of the electromagnetic signals, the communication reliability is improved from a new interference suppression dimension by utilizing a "mode division multiplexing" technology. The system creates a new information interference suppression dimension, can be independently used or combined with other existing interference suppression technologies, is applied to wireless communication of military and civilian aircrafts in various complex electromagnetic environments, and improves the communication reliability.

Description

technical field [0001] The invention relates to an anti-interference communication system based on vortex electromagnetic waves, which belongs to a new type of wireless communication system. Background technique [0002] The future war is no longer a contest of single weapons, but a confrontation between systems and systems, and between systems. The combat mode has changed from the traditional platform independent combat mode to the distributed cluster cooperative combat mode. The swarm uses the distributed communication system for real-time data interaction to achieve tactical information coordination, interference coordination, flight track coordination, firepower distribution and attack coordination to complete combat tasks. In the process of attacking important targets of the enemy, the swarm will also face great challenges in confrontation capabilities. The enemy's interference and suppression of flight formations and communication deception methods are becoming more a...
