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.

국제적인 차량용 레이더는 22~26GHz 대역을 사용할 수 있도록 규정하고 있으나, 최근 전반적으로 위 주파수대역은 이용을 종료하는 추세이며, 차량의 사각지대 및 보행자 감지용 고해상도 차량용 레이더 도입을 위해 밀리미터파 대역 중 77~81GHz대역의 광대역 레이더로 전환할 예정이다. 그러나 현재 국제적으로 71~275GHz대역은 전파천문우주 연구를 위한 업무로 사용하도록 규정되어 있다. 이에 따라 위 대역의 차량용 레이더와 국내 전파천문업무 사이에 간섭이 있을 것으로 예상되어 간섭영향을 분석하고 보호이격거리를 도출하였다.
