| Summary: | Northeast (NE) monsoon season in Malaysia was developed due to conjunction
with cold air outbreaks from Siberia produce heavy rains, strong wind, and high humidity.
This weather condition can affect the radio signal transmission which is crucial to spectrum
user. This work investigates the effect of the wet season due to Northeast season on radio signal
power within Ultra High Frequency (UHF) band at KUSZA Observatory (KO). Three of weather
parameters (wind speed, humidity and rain rate) was considered with the radio signal variation.
Measurement of these weather parameters and radio signal power level (dBm) were collected
using weather station and spectrum analyzer respectively. From the result obtained, we found
that wind speed played a role in radio signal attenuation indirectly. The combination of wind
speed (km/h) along with high humidity (%) and rain rate(mm/s) during NE monsoon season
have given a significant impact to a radio signal. These findings is useful to radio astronomer
to determine the best period for radio astronomical observation with minimum interference
considering weather condition. This study will also beneficial to spectrum user such as mobile
telecommunication, wireless internet and radio broadcasting in managing and improving their
services. |
