1. A radar system for a vehicle, comprising a control unit and a radar transceiver arrangement with at least one ego radar transceiver, where, for the at least one ego radar transceiver, the control unit is adapted to:
determine a present direction of the ego radar transceiver in dependence of a vehicle heading,
determine a reserved frequency band corresponding to the present direction, and to
determine a first extended frequency band comprising and extending beyond the reserved frequency band,
wherein the control unit is further adapted to:
detect presence of an interfering radar transceiver, and to operate the ego radar transceiver in the first extended frequency band in a first case wherein the interfering radar transceiver is not detected during operation of the ego radar transceiver in the first extended frequency band, and to operate the ego radar transceiver in the reserved frequency band in a second case wherein the interfering radar transceiver is detected during operation of the ego radar transceiver.
