Radar system with sub-bands

A radar system for a vehicle, comprising a plurality of radar transceivers and a control unit, each radar transceiver being associated with a main pointing direction and a certain frequency sub-band, where the certain frequency sub-bands together form a certain dedicated frequency band, where the control unit is adapted to:

• define heading intervals which divide a full turn interval 0° 360° into sections,
• assign a corresponding sub-band of the certain frequency sub-bands to each of the heading intervals,
• determine a present vehicle heading,
• assign each of the corresponding sub-bands to each one of the radar transceivers in dependence of the heading interval that comprises the present vehicle heading, and to
• apply a hysteresis when the present vehicle heading passes a border between two of the heading intervals and before performing a shift of the sub-bands,
• wherein the plurality of radar transceivers include a first front corner radar transceiver, a second front corner radar transceiver, a first rear corner radar transceiver, and a second rear corner radar transceiver, wherein each of the first front corner radar transceiver, the second front corner radar transceiver, the first rear corner radar transceiver, and the second rear corner radar transceiver are assigned one of the corresponding sub-bands in dependence of the heading interval that comprises the present vehicle heading, and
• wherein the radar system comprises at least one lateral radar transceiver, where the control unit is adapted to assign one of the sub-bands to each of the at least one lateral radar transceiver that corresponds to one of the sub-bands presently being assigned to a neighboring radar transceiver in dependence of the heading interval that comprises the present vehicle heading.
