초록

본 논문은 짧은 감지 시간과 높은 시간 해상도 특성을 갖는 협대역 채널화 라디오미터의 성능을 이론 수식을 이용하여 검증하였다. 모의실험 결과, 채널화 라디오미터는 광대역 라디오미터에 비해 2.5 dB 우수한 감지성능을 나타내었지만 잡음 영향에 민감한 특성을 갖는다는 것을 확인하였다. 또한 협대역 라디오미터의 신호대잡음비는 도약율과 지터 특성 급격한 특성 변화를 갖으며, 두 파라미터에 의해 선형적인 성능 저하를 나타내었다.

In this paper, the performance of the narrowband channelized radiometer that have a short detection time and high time-resolution was verified based on the theoretical formula. According to the simulation result, the channelized radiometer showed 2.5 dB superior detection performance compared to the broadband radiometer, but is more sensitive to the effects of noise than the broadband radiometer. Also the signal-to-noise of a channelized radiometer was changed dramatically according to the hop rate and jitter effect, which is linearly decreased as the change of two parameters.
