Abstract: A data generation device is provided with environment setting means (200), model setting means (210), image calculation means (220) and data output means (230). The environment setting means sets a radar parameter that indicates a specification of a radar that is a synthetic aperture radar or an inverse synthetic aperture radar. The model setting means sets a three-dimensional model that indicates a shape of a target object to identify. The image calculation means calculates a simulation image based on the three-dimensional model and the radar parameter. The data output means outputs training data in that the simulation image and a type of the target object are associated to each other. In addition, the data output means outputs difference data that indicate a difference between a radar image and the simulation image. The model setting means changes the three-dimensional model based on model correction data inputted based on the difference data.
