Abstract
본 논문에서는 저피탐 특성을 강화하기 위해 암호화된 수열을 확산부호로 사용하는 위성항법신호의 통계적 특성을 이론적으로 분석하고 간섭 저항 성능을 예측한다. 이를 위해 다양한 복소 단위원 심볼셋으로 암호화된 수열의 상관특성을 이론적으로 분석하고, 이를 토대로 기존의 Gold 코드나 Zadoff-Chu 코드와 암호화된 확산부호와의 간섭 저항 성능 차이를 이론적/실험적으로 분석하여 암호화된 확산부호의 적용으로 인한 신호 품질 열화 정도를 규명한다. In this paper, we analyze the statistical characteristic and describe the anti-interference performance of the signal for the LPI-applied GNSS using encrypted spreading code. To do this, we analyze the correlation property of encrypted sequences theoretically having various symbol sets over complex root of unity. We derive the degradation of anti-interference performance of encrypted sequences comparing with Gold and Zadoff-Chu sequences using theoretical and experimental methods.
