| Popis: | A Ka-band Doppler polarimetric cloud radar outfitted with a 20 W GaN solid-state power amplifier is described. The radar has been developed on the basis of its magnetron-based predecessor to investigate the potential of applying solid-state transmitters in low-cost, compact millimeter wave cloud radars. The upgrade has been made through replacing a transmitter alone and adding some extra routines in the digital signal processor to implement the pulse compression technique. The radar sensitivity no worse than −28 dBZ at 5 km has been achieved as the first milestone. Essential design solutions of the radar are described, and test results are presented. |
