ABSTRACT
The intention of this work is to assemble a working radio telescope to determine the surface temperature of the Sun by using widely accessible components. Important components used are an RF detector, an antenna, an Arduino, and a PC with the Arduino IDE all integrated into the manufacturing process. Establishing the correlation between voltage and power output during RF detector calibration is essential for precise data capture. An important part of this procedure is to use off-axis procedures to align the dish antenna with the sun.
Utilizing the drift-scan approach, one of the primary methodologies in this work is examining the Sun's surface temperature. A drift scan involves planned, continuous movement of the radio telescope in a predetermined direction to provide a comprehensive assessment of the Sun's radiation across the sky. By aligning the dish antenna with the sun through the use of off-axis operations and the drift-scan method.
The results demonstrate the successful construction and operation of the Radio Telescope. This includes the determination of the peak power level to be P , the difference between peak power level and the half power level to be M(dB)=1.1dBm, the level of noise to be , peak-power over noise ratio (P/N), and various temperatures, such as, , and(which is the required temperature of the Sun). These findings form the basis for calculating essential parameters like, , and.
