Abstract

In this paper, millimeter-wave radar cross section (RCS) characteristics for high-voltage power transmission line is investigated for the purpose of helicopter collision avoidance, where the RCS measurements were conducted. The dependence of the RCS on a radar incidence angle is also discussed at 35 and 94 GHz. It is found that high RCS can be expected and the angle of the mainlobe and sidelobes coincides with the angle of the Bragg scattering.

毫米波频率下输电线路避碰雷达截面测量

本文以直升机避碰为目的，研究高压输电线路毫米波雷达截面(RCS)特性，并进行了RCS测量。讨论了35 GHz和94 GHz下RCS与雷达入射角的关系。结果表明，该方法可以获得较高的RCS，且主瓣和副瓣的角度与Bragg散射角一致。
