Troubleshooting of dual polarization radar external calibration signal source
This paper briefly describes the calibration link of the dual-polarization weather radar,analyzes the impact of calibration signal source fault on radar echo,dynamic range and noise temperature,proposes a rapid fault diagnosis method by disconnecting the calibration signal source input,lists and analyzes a typical example of dualpolarization Doppler weather radar calibration signal source fault.It also provides the processing method to reduce the damage of calibration signal source by induced lightning strike,and also provides the rapid repair method of the signal source fault in the process of disastrous weather,which provides ideas and reference for other stations to deal with similar faluts.
