Investigation of Multiple-Input-Multiple-Ouput Radar Systems in automobiles
Modern automobiles are already equipped with radar systems. These systems determine the distance, the velocity and the angle of objects in the vicinity of the vehicle. Thereby comfort functions like for example Adaptive Cruise Control (ACC) can be offered. ACC refers to a system, which adjusts the own speed accordingly to the preceding cars.
The radar systems are also used as security systems, e.g. they warn the driver of critical situations. Nevertheless the algorithms used are not yet reliable enough for application as a security system which is able to recognize the end of a traffic-jam, e.g. and to start full braking. Therefore the radar systems and it's signal processing have to be improved further.
My research focuses on the investigation fo Multiple-Input-Multiple-Output (MIMO) radar systems. I study parameter estimation, especially the estimation of the Direction of Arrival, and analyze the performance of different MIMO radar systems.
