Abstract:
The main functions and performance parameters of the IFD Receiver for CINRAD/CB Pulsed Doppler Weather Radar are presented.Techniques embedded in the receiver are IFD(Digitized Intermediate Frequency) ingestion with high sensitivity,highly dynamic range with AGC,low-phase noise frequency Synthesizer,on-line BITE test,real-time calibration.It is designed with the high-stability frequency source and COHO(Coherent Oscillator).The principles of IFD and the system frame receiver are also given.Analyses were made of the capability indicators such as the sensitivity,noise coefficient,and dynamic range.The pulsed Doppler weather radar is C-band weather radar and is currently used for monitoring severe weather in China.
