Abstract: Modern military combat pays more attention to the electronic interference and anti interference, as the important component, the aircraft navigation system is one of the main objects attacked by enemy electronic jamming. In order to simulate the electronic jamming influence on navigation performance of the system, the establishment of an electronic jamming system in aircraft engineering simulator, was designed for the flight simulator interference model and statistical model frame work, and according to the integrity of the system testing and calculation results, the interference was divided into five levels, which not only specified the electrical interference, but also measured evaluation of anti jamming effectiveness. The simulation of navigation system is much more practical, and greatly improves the pilot dealing with electronic jamming disposal capacity, and it has important significance for popularization.

Key words: electronic interference, engineering simulator, navigation system, interference model
