Abstract

In this paper, the method of interference analysis and its simulation have been suggested for the frequency sharing between aeronautical radio navigation systems and Link-16 platforms. In order to get the criteria for interoperability, the algorithm of interference analysis and protection ratio are derived to assure frequency sharing. Also the receiving power of wireless system has been illustrated with the help of radio propagation model of ITU-R Rec. P.1546 in VHF-UHF band. Finally the required receiving power or separation distance between DME/TACAN beacons and Link-16 ground station terminals has been considered based on system link budget in terms of evaluating interoperability as well as actual applications. As a result, if the suggested interference analysis and test set-up are applied to the field trial, it will lead to easy means to make a decision on interoperability over the existing incumbent systems.

본 논문에서는 항행안전시설 주파수와 Link-16(전술데이터링크) 간의 주파수 공유를 위한 간섭분석 방법 및 수치계산 과정을 제시하고 고찰한다. 상호운용성의 기준을 유도하기 위해 주파수 간섭분석 알고리즘 및 간섭 영향의 유무 판단에 필요한 신호-대-간섭 전력비인 보호비의 산출 과정을 기술한다. 또한 VHF-UHF 대역의 전파경로 예측모델인 ITU-R Rec. P.1546을 기반으로 무선시스템의 수신전력 계산 방법을 제시하였다. 시스템 링크 계산을 기반으로 실제 TACAN/DME 비콘과 Link- 16 지상단말기 간의 상호 운용성 보장에 요구되는 수신전력 또는 이격 거리를 구하는 방법과 실제 현장 평가를 위한 적용을 고찰하였다. 결과적으로 제시된 현장시험 구성 및 간섭분석을 적용하면 기존 시스템과의 상호운용성 판단에 용이한 수단이 될 것이다.
