STK software is an important means to achieve three-dimensional visualization of combat scenes. Taking the military joint land, sea, and air operations to rescue hostages as an example, Matlab programming is used to achieve automated modeling of military helicopter combat scenes based on STK. On this basis, the comprehensive terrain module and accessibility tools were applied to simulate and analyze communication signals during combat missions. The radar model was used to analyze the interference effect of electronic jammers on enemy communication, verifying the rationality of the entire combat scenario. The results indicate that this method improves the efficiency of scene modeling.
