Abstract

This study discusses the multiple knife-edge diffraction loss with the receiver and jammer located in the Seoul metropolitan northwestern region. The considered positioning and jamming signals are the GPS L1 C/A signal and several jamming signals such as the wideband Gaussian noise, matched spectrum, and continuous wave signals. To calculate the accurate diffraction effects, the 3-dimensional topography data at the Seoul metropolitan northwestern region was used.

본 논문에서는 수도권 서북부 지역의 3차원 지리정보를 바탕으로 다중예봉모형을 (multiple knife-edge model) 적용해 전파교란기와 수신기의 지리적 위치에 따른 회절손실을 (diffraction loss) 계산하고, 이를 바탕으로 광대역 잡음재밍 (wideband Gaussian null-to-null noise jamming), 스펙트럼일치형재밍 (matched spectrum jamming), 연속파재밍에 (continuous wave jamming) 의한 GPS (global positioning system) L1 C/A (coarse/acquisition) 신호의 여유재밍전력을 (marginal jamming power) 보인다.
