초록

본 논문에서는 GBAS 환경에서 전파위협원 위치 결정을 위한 TDOA/AOA 기반의 효과적인 DOA 추정 기법을 제안한다. TDOA 측정치만을 이용하여 추정한 1차 근사해와 DOP를 이용하여 DOA 추정 범위를 현저하게 감소시킴으로써 효과적으로 전파위협 신호의 DOA를 추정할 수 있다. 제안한 기법을 통하여 비슷한 연산량으로 더 높은 DOA 정밀도를 얻을 수 있으며, 동시에 전파위협원 위치 추정 정확도를 높일 수 있다. 또한 소프트웨어 기반의 시뮬레이션을 통하여 제안한 기법의 성능을 검증하였다.

This paper proposes the DOA estimation method based on TDOA/AOA for jammer localization method in GBAS environment. The proposed method can effectively estimate DOA of jamming signal as the range for DOA estimation is reduced remarkably by using DOP and 1st approximate solution using TDOA measurements only. Through the proposed method, more precise DOA can be obtained and the performance of jammer localization is increased simultaneously. Also, the effectiveness of proposed method will be confirmed through the simulated results.
