Abstract

A method for acquiring information in the spatial environment of a vehicle, comprising: providing at least two radar sensors arranged at different positions at the vehicle; transmitting radar signals by the radar sensors, the radar signals being assigned to the radar sensors; receiving reflected components of the radar signals assigned to the radar sensors at the respective radar sensors and further processing these reflected components of the radar signals as reception information; assigning time information to the reception information obtained from the respective radar sensors, the time information forming a time reference for the reception information; assigning location information to the reception information obtained from the respective radar sensors, the location information forming a location reference for the reception information; and processing the reception information obtained from the at least two radar sensors into common environment information by taking into account the time information and the location information.
