Paper Abstract

To recognize the targets state in a battlefield after shots, it's possible to send a video sensor with the same ballistics than real ammunitions. This article describes the modeling of observation ammunition using simulation workshop CHORALE and AMOCO. Before real trials on a battlefield and to define the final features of an embedded video sensor, it is necessary to modeling each part of the behavior of the ammunition. The goal of this simulation is to know how the ammunition with its movements as the rotation, pitch, yaw can see the proving ground and what values of parameters it is possible to set into the embedded sensor. To perform the simulation, we need of a ballistics model taking into account the geometric form of the projectile. This ammunition flights over a battlefield so we need a realistic 3D scene model taking into account the atmospheric conditions, real target, geometric target and all existing things on a real proving ground as building, forest and so on. The frame seen by the sensor is modified by its transfer function. The video sensor model takes into account lot of functional parameters as Optic, Detector and electronic function. An algorithm takes place at the incoming step in the sensor model and takes into account the rotation during the integration time. Each model calculates independently.
