Development of an Antarctic Atmospheric Radar

We briefly review the system outline and technical developments for the Antarctic atmospheric radar constructed at Syowa Station (69°S, 40°E). The radar has achieved equivalent sensitivity to that of the MU radar in Japan while reducing its power consumption to less than one thirds of that. Newly developed algorithms for adaptive clutter rejection and beam de-broadening are introduced to alleviate difficulties imposed by the environmental and the operational conditions unique to this facility.
