Abstract
TRI-D imaging, a three-dimensional interferometric beamforming technique, is currently used in lightning research. In this thesis, we process signal data obtained through the Low Frequency Array (LOFAR) using TRI-D imaging, and analyze the reliability of the 3D polarization data generated by TRI-D interferometry. Our results show that the distribution of polarization directions deviates from the expected uniform distribution. To explore the factors influencing these imaging results, we modified the antenna function and calibration files, analyzing their effects across different locations. The analysis reveals significant variations in their effects for the different locations. Finally, we analyzed the relationship between the relative positions of the antennas and the polarization distribution characteristics of the background radiation. The results demonstrate a strong correlation between antenna placement and the deduced polarization data distribution.
