| Summary: | Abstract—The preliminary analysis involving comparison
between radar derived attenuation using an S-band
meteorological radar and measured signal of RazakSAT’s
X-band satellite link is presented. The radar data employed was
attained from the Malaysian Meteorological Department’s
(MMD) terminal Doppler weather radar installed strategically
in the vicinity of Kuala Lumpur International Airport (KLIA).
The X-band (8 GHz) satellite-Earth signals of Malaysian
RazatSat’s collected at the National Space Agency (NSA) space
center have been analyzed and studied. The vertical
polarization S-band radar reflectivity information was used to
calculate the likely rain attenuation along the RazakSAT
satellite propagation paths. This was carried out by first
converting the radar reflectivity values into rainfall rate using
the established Z-R relations of Marshall-Palmer equation and,
afterwards, by evaluating the slant path attenuation through
the assimilation of the specific rain attenuation derived at the
rainfall rate. |
