Abstract

This paper describes the product of search and rescue system with dynamic model. This spread spectrum system based new standard of COSPAS-SARSAT is results of RF signal generation and transmission. we will test performance evaluation which implement signal process adapting Dynamic model and we will adapt the CAF model using TDOA and FDOA relationship.

본 논문은 동역학 모델을 적용한 양방향 군 탐색구조 시스템의 시작품 제작에 대한 내용을 기술한다. USRP 개발 플랫폼과 단말기와 위성간의 통신을 상용 LTE망에 COSPAS-SARSAT 규격인 Spread Spectrum 방식의 신호체계를 USRP에 구현한 결과이다. 또한 구현된 결과의 정당성을 확인하기 위해 동역학 모델을 적용한 COSPAS-SARSAT 기반의 RF신호 처리를 USRP 테스트베드에 적용하여 실제적인 성능평가를 수행하였다. 향후 TDOA와 FDOA의 상관관계를 이용하는 CAF 알고리즘을 이용하여 보다 정확한 지상측위에 적용하고자 한다.
