  • Apparatus and method for compensating for doppler expansions
    Patent number: 11747460
    Abstract: An apparatus (100) for compensating for weather-independent Doppler expansions in radar signals of a weather radar system (200) is disclosed. The device comprises: a receiving device (110) for receiving a representation (50) of the radar signals, a calculation device (120) and a compensation device (130). The representation includes pixels of a range Doppler matrix. The calculation device (120) is designed to calculate azimuth angles (Azi) for the pixels (75) by means of fine bearing. The compensation device (130) is designed to correct weather-independent Doppler shifts for the pixels (75) 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 (150).
