초록

연안에서 선박의 안전한 항행과 관제를 위해 선박간 또는 선박과 관제소간의 항행정보를 교환할 수 있도록 하는 AIS(Automatic Identification System)는 운용 방식(Low setting, High setting)에 따라 서로 다른 송신 출력 크기를 가지며, 1 ms(Transmitter Setting Time)안에 각각의 최종 출력 크기 의 20% 이내로 도달하도록 하는 동작 성능을 요구한다. 본 논문에서는 이와 같은 AIS의 송신 출력 특성에 부합할 수 있도록 전력 증폭기 모듈에 적절한 궤환 회로를 제안하고 이를 설계, 제작하였다.

AIS(Automatic Identification System), was suggested for the navigational data communication between ships and between ships and shore stations for the better safety of navigation, and it requires two different the transmitting output power level depending on its operating mode. According to ITU's recommendation, these levels should reach within 20 % of its final value in 1 ms. In this paper, an adequate feedback control circuit for power amplifier module is designed and implemented.
