This data set is the radar meteorological observation data of Pingliang Lightning and Hailstorm Experimental Station of the Chinese Academy of Sciences, including the observation data of Gansu Pingliang dual polarization Doppler radar in 2005
The observation period began on June 4, 2005 and ended on November 1, 2005
The dual polarization Doppler radar receiver is a digital intermediate frequency receiver, with the transmitter being a traveling wave tube pulse compressor. The polarization system is a dual channel simultaneous receiver and horizontal channel, with a separate transmitter (interchangeable). The signal processor is RVP900, and the antenna controller is RCP8
The obtained echo parameter intensities include velocity V, spectral width W, intensity reflectance 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
