초록

본 논문에서는 저궤도 위성 원격측정데이터 신호 수신을 위한 S-대역 위상배열안테나를 제안하였다. 제안된 안테나는 16개의 부배열 조립체, 16개의 능동회로모듈, 수직 급전회로망 및 제어/전원반으로 구성되며 고각 방향으로 빔틸트가 수행된다. 개발된 안테나는 고각 축과 위성 궤적을 일치시키고 개구 중심을 위성 궤적 상의 최대 고각을 바라보도록 하여 정밀한 위성 추적을 수행하였다. 저궤도 위성의 궤적은 위성점 계산을 통하여 정확하게 산출하였다. 위성 추적 시험은 최대 고각을 기준으로 ±30° 범위에서 수행되였다. 위성 추적 시험 결과 최대 고각에서의 S/N비는 16.5 dB이고 Eb/No는 13.3 dB를 얻었다. 수행된 위성 추적 결과는 사전 시스템 분석 결과와 잘 일치함을 확인하였다.

This paper presents a S-band phased array antenna system for receiving LEO satellite telemetry signals. The proposed antenna, which is performed to be beam-tiled along the elevation direction, consists of 16 sub-array assemblies, 16 active circuit modules, a perpendicular feed network and a control/power unit. In order to precisely track an LEO satellite, the developed antenna is placed with its elevation axis along the projected trajectory of the satellite on the earth. The center of antenna aperture is facing to the maximum elevation angle in the LEO trajectory. The beam-tilted angles for tracking LEO satellite are obtained by calculating accurately satellite points. Satellite tracking measurements are carried out in the range of ±30° with the respect to the maximum elevation angle. The S/N ratio of 16.5 dB and the Eb/No of 13.3 dB at the maximum elevation angle are obtained from the measurements. The measured result agrees well with the pre-analyzed system margin.
