Abstract: The present disclosure relates to exemplary embodiments of radar systems for providing increased robustness against radar interference transmissions and methods for controlling such radar systems. The radar system comprises at least one radar antenna configured at least for receiving a radar signal, a radar signal dividing means, a first receiver device and a second receiver device. The first receiver device is configured for monitoring a first frequency range and the second receiver device is configured for monitoring a second frequency range, wherein the second frequency range is wider than the first frequency range and the first frequency range is a subset of the second frequency range. The second receiver device is configured for measuring interference levels within the second frequency range. The present disclosure further relates to exemplary embodiments of methods for controlling the radar system, wherein the methods refer to measuring interference levels within the second frequency range, analysing measured interference levels, determining favorable frequency channels within the second frequency range in respect to interference level and possibly changing operating frequency channel in respect to measured interference levels.

Abstract: The present invention relates to a radar system for a vehicle, a method for controlling a radar system, a computer program product, and a vehicle comprising such a radar system. The radar system comprises an antenna arrangement for transmitting and/or receiving electromagnetic waves, a power supply connected to the antenna arrangement, the power supply being arranged to supply the antenna arrangement with operating power. The radar system further comprises an antenna controller connected to the antenna arrangement, the antenna controller being configured to control an operation of the antenna arrangement. The radar system also comprises an auxiliary power source connectable to the antenna arrangement for supplying the antenna arrangement with supplementary operating power so to increase an output power of the antenna arrangement, and a boost controller connected to the auxiliary power source and to the antenna controller, the boost controller being configured to connect and disconnect the auxiliary power source to/from the antenna arrangement. Hereby presenting a radar system capable of increasing the maximum range of the antenna arrangement during an arbitrary period of time without suffering from too heavy penalties in terms of increased weight or cost.
