1. An apparatus for compensating for weather-independent Doppler expansions in radar signals of a weather radar system, the apparatus comprising:
a receiving device for receiving a representation of the radar signals, wherein the representation comprises pixels of a range Doppler matrix;
a calculation device which is configured to calculate azimuth angles (Azi) for the pixels by fine bearing; and
a compensation device which is designed to correct weather-independent Doppler shifts for the pixels based on the calculated azimuth angle (Azi; AziMopu) and thus to compensate for the weather-independent Doppler expansions and to provide them as a compensated representation.
