Abstract:Using the method of illustration method, the compositions, characteristics and roles of RDA adaptation parameters for CINRAD/SA weather radar are introduced systematically.The important applications of adaptation parameters for CINRAD/SA weather radar in radar maintenance and calibrations are embodied with an instance, to help radar maintenance technicians to use the adaptation parameters well.Experiences show that adaptation parameters play an important role in intelligent management, operational control, maintenance, calibrations, alarms, signal processing and data generation, etc., of CINRAD/SA weather radar.To understand systematically and apply fully adaptation parameters has practical significance to the efficient and reliable operating of weather radar.
