Abstract: The present invention relates to a method (1o) for determining an elevation angle of an electromagnetic sensor mounted in a vehicle, wherein the method comprises the steps of exciting (11) a transmitter of the sensor with a plurality of different frequencies such that the transmitter radiates a plurality of first electromagnetic signals corresponding to the plurality of frequencies onto a target arranged in the field of view of the sensor, wherein each of the plurality of first electromagnetic signals is radiated at a different angle relative to the transmitter; receiving (12), by the sensor, a plurality of second electromagnetic signals being reflections of the first electromagnetic signals at the target; determining (13-17) the elevation angle of the sensor based on the second electromagnetic signals. The invention also relates to a corresponding sensor and a computer program for performing the method.
