Abstract

Radio Frequency Interference (RFI) is a very important issue to address in order to setup a radio astronomical facility. We have successfully done the site testing on some important and strategic places in Malaysia and we present the results in this paper. We will implement the usage of the Spectral Kurtosis (SK) estimator in order to eliminate the RFI. In this paper, we present the results of the 3-D and basic statistical Kurtosis analysis method that we have applied to our RFI data. We have found that this method allows us to conclude the RFI level at the individual sites without having to look at the graphs of the frequency spectra. In this paper, we will also discuss the possibilities of the planned science goals that can be done with the future radio telescope facility in Malaysia, including studies in cosmology and space weather.
