Abstract
The invention describes a radar system consisting of a plurality of subcomponents each individually having all components of a radar device which comprise at least transmitters, receivers, a mixer and a phase locked loop, wherein an individual phase code is generated for each transmitter; and transmitters and receivers of all subcomponents of the radar system together provide a virtual overall arrangement according to the Multiple Input Multiple Output method, wherein at least one virtual sub-arrangement of the overall arrangement, provided by a combination of transmitters of a subcomponent and receivers of a subcomponent, has at least one overlapping column or one overlapping row with another virtual sub-arrangement of the overall arrangement, wherein the at least other virtual sub-arrangement is provided by another combination of transmitters of a subcomponent and receivers of a subcomponent.
