| Summary: | Precision guide ammunition has become the main mode of attack in modern warfare, with radar precision guided weapons widely used. In the field of countering radar precision guide weapons, smoke screen jamming has attracted much attention due to its advantages such as ultra-high-cost-effectiveness. In order to analyze the feasibility and main performance indicators of smoke screen jamming against radar precision guided weapons, this paper study the jamming principle of smoke screen against radar precision guide weapons. Taking radar air-to-air missile as an example, the simulation model for the shielding effect of smoke screens on radar air-to-air missile’s operational is established through modeling and simulation methods by integrating the attenuation effect of smoke screen on radar guidance transmitter signal/echo signal into the ballistic simulation process, and the operational effect and performance index of smoke screen shielding are simulated. The research results indicate that indicators such as smoke transmittance, smoke shielding time and smoke release timing have a significant impact on the combat effectiveness of smoke screens. Fighter jets can effectively reduce the probability of being hit and improve their survivability during combat by releasing smoke screens and implementing masking interference on the radar detection signals of incoming missiles.
