Evaluation of a 35-GHz Radar for Cloud and Precipitation Research in SCHeREX-Experiment

HMBQ radar is the first millimeter-wavelength (8mm) cloud radar with Doppler and polarization in China. Several new techniques like coherence accumulation, polarization and pulsating compressive had been applied in this radar. The minimum effective radar reflectivity factor of water cloud that is measured by this radar at a range of 10 km is estimated to be -40dBz. During May to September in 2008, HMBQ radar was situated in DongGuan, GuangDong Province for the SCHeREX experiment to observe clouds and obtained much valuable information. Some examples of cloud structures are presented in the experiment, also presented here is the liquid water content retrieved by this radar.
