Since the radar stations of CINRAD/SA are usually located on mountain tops in the suburb where the ground impedance is extraordinarily high and radar bases are constructed of reinforced concrete instead of iron towers, lightning protection is very important in those radar stations. While the lightning protection of the early CINRAD stations has adopted the same lightning protection system as at the WSR88D radar sites, which is a single vertical lightning pole on the radome top, lightning damages repeatedly happened to those early CINRAD stations. The lightning damages to the Guangzhou CINRAD station are analyzed mainly in terms of radar techniques combined with lightning protection techniques, and an efficient improved lightning protection system to the CINRAD/SA is discussed.
