TThis data set is the radar meteorological observation data of Pingliang lightning and hailstorm test station of Chinese Academy of Sciences, including the observation data of dual polarization Doppler radar in Putian, Fujian Province in 2008.
The observation time is from August 12, 2008 to September 18, 2008.
The dual polarization Doppler radar receiver is a digital IF receiver, the transmitter is a TWT pulse compressor, the polarization system is a dual channel receiving and transmitting mode and a horizontal channel, the single transmitting mode (interchangeable), the signal processor is rvp900, and the antenna controller is rcp8.
The echo parameters obtained are velocity V, spectral width W, intensity reflectivity difference, differential transmission phase shift, ratio difference, correlation coefficient and linear depolarization ratio LDR.
Autonomous production (instrument observation)
Raw data, unprocessed
The dual polarization Doppler radar has a wavelength of 3cm, a transmission pulse width of 1us or 2us, a receiver sensitivity of -109dBm, a transmission waveform of horizontal or 45 degree linearly polarized waves, an intensity signal accuracy of 0.5dB, and a phase signal accuracy of 0.1 º
