[0002] Communication jamming signals are a crucial component of a complex battlefield electromagnetic environment and play a decisive role in the success of disrupting enemy communications. To ensure effective communication jamming during actual combat, efforts must be made to develop communication jamming methods that closely resemble actual combat. Some international communication countermeasure training models, in addition to utilizing real communication countermeasure equipment, also rely heavily on various signal simulators, computer simulation technology, distributed interactive sensing technology, and forces capable of simulating hypothetical enemy forces. The goal is to create a realistic battlefield electromagnetic environment, enabling closed-loop assessment of communication countermeasure training within a complex electromagnetic environment, thereby improving combat capabilities in such environments.

[0003] At present, many large training bases have set up complex electromagnetic environments and are equipped with a full range of equipment and facilities, which can enable relatively comprehensive communication confrontation training. However, the communication confrontation teams of subordinate grassroots units lack effective training and evaluation methods. Although they also rely on various electromagnetic deduction and simulation software for training and software deduction and evaluation exercises, the simulation process still cannot be compared with the actual communication confrontation closed-loop training, and cannot further restore the effectiveness of the interference methods in the actual confrontation process.
