5. Conclusion
This chapter discusses the aviation applications of TDWR. This radar issues microburst
alerts which are crucial in the assurance of aviation safety. A typical case of microburst
detection by TDWR in association with intense thunderstorms is described first in this
chapter. Then the applications of TDWR in the alerting of windshear and turbulence are
described. Windshear is alerted through the calculation of windshear hazard factor, which
is a rather well established technology. On the other hand, the use of spectrum width data
from the radar in the alerting of turbulence has a relatively shorter development history,
and the technology is under exploration in Hong Kong.
Study is underway in Hong Kong to use X-band radar in the alerting of windshear and
turbulence on experimental basis at the Hong Kong International Airport. The use of long-
range S band radar in the alerting of turbulence for enroute aircraft is also under study.
Such progress of these studies would be reported in the future.
