Statistical analysis for Terengganu forward scatter radar seaside clutter
Nor Najwa Ismail1, Nur Emileen Abd Rashid2, Zuhani Ismail Khan3.
The statistical analysis for Terengganu, Malaysia seaside clutter is presented in this paper.
The measured clutter data were collected using a prototype of forward scatter radar (FSR)
micro-sensor network with very high frequency (VHF) and ultra-high frequency (UHF) bands.
Four categories of clutter strength were recorded during the measurements, which are low,
medium, strong and very strong clutter. The classes were divided according to the wind
speed occurred during the measurements period. The analysis is to determine the best-fit
distribution model for the measured clutter data. Four types of distribution models are used
in this analysis, which are Weibull, Gamma, Log-Logistic and Log-Normal distribution. One
of the goodness of fit (GOF) tests called root mean square error (RMSE) is used to prove
which distribution is a better fit to the probability distribution of the measured clutter data.
The obtained results show that for 64 MHz with all clutter level strength, Weibull distribution
provides better fit and records the lowest RMSE. Weibull distribution also fits best to the
clutter data for low clutter of 151 MHz. However, for the rest of clutter level strength for 151
MHz, Gamma distribution is the best-fitted model with lowest RMSE values. Log-Logistic
distribution proves to be the best fitted model to all clutter level strength of clutter data for
434 MHz with smallest RMSE values.
