Abstract

An analog to digital converter(: ADC) has been designed to extract video signals of marine X-band radar and convert to digital signals in order to produce rainfall information. X-band weather radars are suitable for high temporal-spatial resolution observations of rainfall over local ranges but they are very expensive and require professional management. The marine radars with 10-2 cost facilitate data collection and management as well as economic benefits. To validate the usefulness of the developed ADC, comparative observations were made with weather radar for short term precipitation cases. The rainfall distribution of marine radar observations are consistent with that of weather radar within a radius of 15 km. This demonstrates the usability of marine radar for rainfall observations.

선박용 X 밴드 레이더의 영상 신호를 추출하고 디지털 신호로 처리하여 강우 정보를 생산하는 변환기(Analog to Digital Converter, ADC)를 설계하였다. X 밴드 기상 레이더는 국지적 범위에 대한 강우의 시공간적 고해상도 관측에 적합하지만 가격이 매우 비싸고 전문적인 관리가 필요하다. 이에 비해 10-2 비용의 선박용 레이더는 경제적인 이득뿐만 아니라 자료 수집 및 관리를 용이하게 한다. 개발한 변환기의 유용성을 검증하기 위해 단기 강수 사례에 대한 기상 레이더와 비교 관측을 수행하였다. 선박용 레이더의 강우 관측 결과는 반경 15 km 이내에서 기상 레이더와 일치하였다. 이를 통해 선박용 레이더의 강우 관측 활용성을 입증하였다.
