The Dependence of Log Periodic Dipole Antenna (LPDA) and e-CALLISTO Software to Determine the Type of Solar Radio Burst (I -V)

Abstract

Solar radio burst originated at the layer of the atmosphere where the Geo-effective disturbance occurred which energy will be released in solar flares and Coronal Mass Ejections (CMEs) will be launched. Solar Radio Burst can be divided into 5 types and determined by using the Log Periodic Dipole Antenna (LPDA) and e-CALLISTO system. The LPDA was set up in a 45-870 MHz range in frequency and has maximum boom length 5.45m. Besides that, it has minimum scale factor, τ=0.76 and maximum at τ=0.98. We put some effort to construct suitable with designs, high specification and practical enough with the size of boom length as the conclusion the scale factor that suitable with this design is 0.8118 as a directivity of an antenna. LPDA has 19 elements which using two (2) aluminium rod with 7.01dB gain. The antenna has a function to receive the signals then connected to the low noise amplifier and e-CALLISTO spectrometer completes it as a system. A CALLISTO (Compound Astronomical Low-Cost- Low-Frequency Instrument for Spectroscopy Transportable Observatory) spectrometer was used to figure out the dynamic of solar corona which in metric and decimetric wavelength radio observation and the main objective of this study was to study how the solar radio burst can be detected by using LPDA (Malaysia) and e-CALLISTO (ETH Zurich, Switzerland) which were set up in a different location.In this paper, the potential of Malaysia be one of the candidates to contribute a good data will be highlighted and we will focus more on performance evaluation and visualization data.
