Abstract
The detection of high-voltage power lines plays an important role in helicopter flight safety. Firstly, geometric model of high voltage power lines is established, and its Bragg scattering characteristics are introduced through theoretical analysis. Then, Radar Cross Section (RCS) of the high voltage line is simulated in millimeter wave band, and the Bragg scattering pattern is obtained, Bragg scattering characteristics of the high voltage line varying with frequency are analyzed. Finally, we compare full polarization scattering characteristics of the high voltage power line at 35 GHz with 94 GHz, and analyze the reflection characteristics of circular polarized waves by cylinders and high voltage lines.
