Abstract (in Japanese) (See Japanese page) 
(in English) This report discusses the antenna polarization characteristics of the helicopter obstacle detection small transmitting power 76 GHz millimeter-wave radar system. The purpose of the on-board radar is to detect and avoid obstacles such as high-voltage power lines and towers that may affect flight safety. To improve the power line detection characteristics of the radar system, the polarization characteristics of the power line radar cross sections (RCS) are measured inside the anechoic chamber. Firstly, the specification of the small transmitting power millimeter-wave radar, which requires no license, is briefly explained. Then, the RCS measurement set-up using the 76 GHz millimeter-wave radar systems and two-types of the power lines are shown. The measured RCS characteristics of the power lines are fundamentally the same trends as the previously reported at the 35 GHz and 94 GHz. However, it is confirmed that the RCS values of the horizontal polarization are almost same values as that of the vertical polarization in certain conditions.
