Multi-source, multi-object and multi-domain (M-SOD) electromagnetic interference system optimised by intelligent optimisation approaches

摘要

With the wide use of electromagnetic information equipment, a larg number of wireless radiation systems coexisting in the same region produce intentional or unintentional interference on electronic receivers. For the purpose of intentional electromagnetic interference, it is necessary to realisethe efficient suppression of other receivers at little cost. When multipletransmitting sources are used to interfere with multiple receivers, the parameters of multiple transmitting sources are required to be comprehensivelyoptimised and set so as to achieve a desired high-efficiency interference.Therefore, we propose a novel method to optimise the setting of parameters of a multi-source, multi-object and multi-domain (M-SOD) interference system based on intelligent optimisation approaches. Furthermore, this study also builds anintelligent optimisation model, which contains multiple transmitters andreceivers which involved many parameters include position, direction of space domain, frequency, bandwidth, and power. Then the model is abstracted to theproblem of single-objective optimisation with constraints and optimised through a traditional GA and an improved FWA method. The extensive experiments andcomparisons show that the proposed algorithm is an effective approach forsetting the parameters of an M-SOD electromagnetic interference system andsuperior to the conventional method.
