In this paper, we propose a technique for generating maneuvering trajectories for the trajectory prediction of maneuverable ballistic missiles. To predict the rapid terminal trajectory of a maneuverable ballistic missile, a large amount of flight data is required; however, there is a significant lack of actual flight data observed from test-launch, posing challenges for research. While methods for generating maneuvering trajectories using a 3-degree of freedom (DOF) model and an angle of attack approximation model have been primarily employed, they have two major limitations. First, they arbitrarily limit the maximum angle of attack. Second, they fail to consider the fin deflection angle. To address these limitations, this paper proposes a trimmed aerodynamic model. This model, developed through trim condition analysis, limits the maximum angle of attack based on flight conditions and accounts for the fin deflection angle. Furthermore, a Pseudo-5 DOF simulation model was configured, and a framework for generating various maneuvering trajectories was constructed using a shooting method.
