Abstract

To efficiently manage forest resources, it is essential to deploy multiple unmanned aerial vehicles equipped with various sensors simultaneously. Consequently, the ground control station antenna should not only maintain continuous tracking of the target station but also minimize the impact of radio interference on other unmanned aerial vehicle stations. In this paper, we presented beam forming techniques based on the VPR algorithm within a ground control station constructed using a phased array antenna system. Through simulation experiments in diverse unmanned aerial vehicle operating environments, it was demonstrated that the presented method enables not only the continuous tracking of operational unmanned aerial vehicles but also the suppression of radio interference by establishing a continuous pattern null for multiple operational radio interference sources.

산림자원의 효율적인 관리를 위한 정보획득을 위해서는 서로 다른 센서를 장착한 다수의 무인항공기가 동시에 운영되어야 한다. 이에 따라 지상제어국 안테나는 지속적으로 대국에 대한 추적을 수행해야 할 뿐만 아니라 타 무인항공기에 대한 전파간섭 영향을 억제해야 한다. 본 논문에서는 위상배열안테나 시스템을 기반으로 구축된 지상제어국에 있어, VPR 알고리즘을 기반으로 지속적인 추적 및 전파간섭 억제를 위한 빔 형성 기법에 관하여 연구하였다. 다양한 무인항공기 운영 환경에 대한 모의실험 결과, 제시된 기법을 기반으로 운항중인 무인항공국에 대한 지속적인 추적을 할 수 있을 뿐만 아니라, 다수의 전파간섭원에 대해 지속적인 패턴 널을 형성하여 전파간섭을 억제할 수 있음을 확인하였다.
