摘要： A dual polarization radar system is calibrated based on real-time data measurements, such as measured horizontal and vertical reflectivities, ZH and ZV. In this regard, the radar system analyzes the reflected power measurements to identify which measurements are associated with reflections from a respective spherical object. Using such measurements, the system determines a system differential reflectivity value, and combines such value with reflected power measurements for calibration. Since the calibration is based on real-time data measurements, the calibration process may run simultaneously with the collection of weather data. Thus, it is unnecessary to suspend weather monitoring activities in order to perform the calibration, and the calibration can be run as often as is desired without interfering with such weather monitoring activities. Further, the calibration process is immune to the weather events within range of the radar system. Accordingly, it is possible for the calibration to be performed at any time and without interfering with the weather monitoring activities regardless of the types of weather events occurring within the vicinity of the radar system.
