본 논문의 목적은 전파 간섭계의 검출 감도를 향상시키는 것이다. 고감도 전파 간섭계를 위해서는 광대역 신호처리 기술의 개발이 필요하다. 고차 샘플링 기술은 고가의 광대역 변환 시스템보다 더 넓은 대역폭을 달성할 수 있습니다. 오버 샘플링 기법은 11.89레벨 양자화 샘플링에서 양자화 손실을 3.99%에서 4%로 개선할 수 있습니다. 또한, 디지털 필터는 샘플링 과정에서 직사각형이 아닌 주파수 응답으로 인해 발생하는 폴딩 노이즈를 줄일 수 있습니다. 고차 샘플링, 오버 샘플링 및 디지털 필터링 기법을 구현함으로써 광대역 및 저손실 A/D 변환 시스템을 구현할 수 있음을 확인하였다. 본 논문에서는 전파천문학을 위한 이러한 첨단 기술에 초점을 맞춘 주요 특징을 자세히 제시합니다.

Abstract: The purpose of this paper is to improve the detection sensitivity of radio interferometry. The development of wideband signal processing techniques is necessary for high-sensitivity radio interferometry. The higher-order sampling technique can achieve wider bandwidth than expensive wide-baseband conversion system. The over sampling technique can improve the quantization loss from 11.89% to 3.99% at the 4-level quantized sampling. Moreover, the digital filter can reduce the folding noise incurred by the non-rectangular frequency response at a sampling process. It is confirmed that the wideband and low-loss A/D conversion system may be realized by implementing the higher-order sampling, over sampling and digital filtering techniques. In this paper, the key features focusing on these advanced techniques for radio astronomy are presented in detail.
