Anti-Collision Radar on Car Bumper

Anti-collision system (or collision avoidance system) is a safety system found in cars which detects danger and reduces possibility or severity of collision. In this application note, we consider anti-collision system which uses radar at 77 GHz mounted on a car bumper. The simulations will be performed using Domain Decomposition Solver (DDS), WIPL-D product dedicated to simulating electrically very large problems. The anti-collision radar is modeled by using 4×4 patch array. The model of the bumper was imported to WIPL-D Pro CAD and the patch array has been added to emulate a real world antenna placement scenario. All of the simulations have been performed on a powerful desktop machine with two 12-core CPUs and significant amount of RAM. All simulation times are under 1h in the DDS.
