This first half of this paper gives a basic understanding of thermal imaging of microwave fields over plane surfaces. The electromagnetic radiations emanating from a microwave source are made to fall on a thin absorption (resistive) screen. These waves are amplitude modulated. The waves falling on the screen result in temperature rise of the screen. Thermal images of the screen are taken by an IR camera at some fixed frame rate and hence a thermal movie is recorded. Amplitude images of the thermal movie determine the power pattern of these waves at the screen location cameras or more popularly known as infrared cameras. This second half of this paper gives a brief review of thermal imaging of microwave fields over plane surfaces gives a basic understanding of thermal imaging of Microwave fields over plane surfaces.
