Simulating complex environments for the assessment of millimeter waves sensors

Guidance of weapon systems relies on sensors to analyze targets signature. Defense weapon systems also need to detect then identify threats also using sensors. One important class of sensors are millimeter waves radar systems. However, such sensors systems are so complex that they need simulation to be tested. In this context, the SE-Workbench-RF tool is presented. The basic technical choices toward an efficient solution for radar simulation are discussed and the newly included GPU implementation is described from an accuracy and computation costs point of view. RBGM radar simulation is presented as an application example of the computation kernel.
