Abstract
The global automotive radar is regulated to use the 22GHz~26GHz band. However, it plans to move to the 77~81GHz band of a broadband radar in the millimeter wave for the high resolution of pedestrian sensing and blind spot. On the other hand, the 71~275GHz band is regulated to use a radio astronomy service. The interference is predicted between an automotive radar and a radio astronomy service. Therefore, this paper analyzed the interference impact of the automotive radar on the radio astronomy service and then obtained separation distance for the protection of the radio astronomy service.
