English Abstract
In this work we studied Solar Radio Bursts were amongst the first phenomena identified as targets for radio astronomy.
Solar radio bursts at frequencies below a few hundred MHz were classified into 5 types in the 1960s:- Type I, Type II, Type III, Type IV, and Type V.
The classification of radio burst is based primarily on its appearance on a dynamic spectrum.
We have studied, analyzed these bursts and identified the significant frequencies and classified it especially of Type III bursts are the most common type of solar radio activity; they are referred to as fast drift bursts from high to lower frequencies, this type divided into two types are :- Type III/1 and Type III/2 .
We have opened the files in extension *.spd (Sky Pipe Data) of type III bursts by writing a Visual Basic language program then using MATLAB language to find Fast Fourier Transform (FFT), Power Spectral Density (PSD) and the significant frequencies of type III solar radio bursts.
The Results showed that the significant frequencies of the solar radio burst for type III/1 found to be within the range of (170Hz ≤ ƒ ≤ 195Hz), while that for type III/2 found to be within the range of (60 Hz ≤ ƒ ≤ 85 Hz).
