Abstract

The radiation characteristics in millimeter-wave band of the metal objects are complicated particularly those with complex three-dimensional structures. The complicated electromagnetic environment, in which the stereoscopic metal objects reflect the radiation energy in all directions with arbitrary incident angles, makes this problem even more challenging. In this paper, the surface panel method and the ray tracing theory are used to analyze the bins of the stereoscopic metal targets surface and their corresponding radiation sources in the reflection path. In addition, in 3mm band the radiometric images of the metal ball and the metal column are given by practical measurements. By comparing the single radiation scanning curves of the selected metal targets, the influence of the three-dimensional structures on the brightness temperature was analyzed and verified. Furthermore, the differences of the radiation patterns of different stereoscopic structures are also summarized.
