The electromagnetic environment on the battlefield is an important factor affecting the combat effectiveness of equipment, and using electromagnetic environment software for equipment testing and training has become one of the current mainstream methods. In response to the problem that the original simulation training system can only set initial conditions and be automatically executed by computers according to the model, and cannot be combined with equipment for electromagnetic countermeasure support training, an equipment testing electromagnetic environment analysis and simulation deduction system is constructed. It has the characteristics of combining equipment strike, “man in the loop” simulation exercise method, flexible and dynamic combat deduction, etc., and compensates for the single content of simulation exercises and the disadvantage of fixed processes.
