  • Apparatus for measuring circular depolarization ratios in a weather radar
    Patent number: 9494681
    Abstract: An apparatus and method for the pre and post processing of radar signals to allow for improved measuring of circular depolarization ratio data in a weather radar. The system uses a phase shifter, which is periodically calibrated to ensure proper polarity, to alter the transmission phase of one channel of a radar transmission output. Reflectivity signals are then processed in accordance with rules dependent upon the transmission phase shift to reliably extract circular depolarization ratio (“CDR”) data from the reflectivity signals. CDR data is used to enhance hydrometer recognition in a weather radar system.
    Type: Grant

    Date of Patent: November 15, 2016
    Assignee: Enterprise Electronics Corporation
