研究目的
To analyze and confirm the Planck, Wien, and Rayleigh-Jeans Theories for blackbody radiation in the context of passive millimeter wave imaging (PMMWI) systems by running their formulas on MatLab Program with different temperatures for frequency or wave length at x-axis and for spectral radiance at y-axis.
研究成果
The study confirms the validity of Planck’s Blackbody Law and its approximations by Wien and Rayleigh-Jeans Laws through computational analysis. The results align with literature, demonstrating the effectiveness of these theories in analyzing blackbody radiation for PMMWI systems. The study highlights the importance of temperature and emissivity in imaging contrast and supports applied PMMWIS analysis.
研究不足
The study is theoretical and relies on computational analysis without experimental validation. The applicability of Rayleigh-Jeans Law is limited to low frequencies.
