Abstract

Because the USV(Unmanned Surface Vehicle) is capable of remote control or autonomous navigation at sea, it can secure the superiority of combat power while minimizing human losses in a future combat environment. To plan the technology for the development of USV, the trend analysis of related technology and the selection of promising technology should be preceded, but there has been little research in this area. The purpose of this paper was to measure and evaluate the technology trends quantitatively. For this purpose, this study analyzed the technology trends and selected promising/declining technologies using topic modeling of papers and patent data. As a result of topic modeling, promising technologies include control and navigation, verification/validation, autonomous level, mission module, and application technology, and declining technologies include underwater communication and image processing technology. This study also identified new technology areas that were not included in the existing technology classification, e.g., technology related to research and development of USV, artificial intelligence, launch/recovery, and operation, such as cooperation with manned and unmanned systems. The technology trends and new technology areas identified through this study may be used to derive key technologies related to the development of the USV and establish appropriate R&D policies.

무인수상정은 해상에서 원격 제어 또는 자율항해가 가능한 선박으로 미래 전투 환경에서 인명 손실을 최소화하면서도 전투력 우위를 확보할 수 있는 수단이다. 무인수상정 개발에 필요한 기술을 기획하기 위해서 관련 기술의 동향분석 및 유망기술 선정이 선행되어야 하나, 관련된 연구가 미흡하다. 본 연구의 목적은 무인수상정 관련 기술 동향을 정량적으로 분석하는 것으로, 토픽모델링을 이용하여 무인수상정 관련 세부기술을 도출하고, 유망/쇠퇴기술을 선정하였다. 분석 결과 유망기술로는 제어, 항법을 비롯하여 확인/검증, 자율수준, 임무 모듈, 활용 기술이, 쇠퇴기술로는 수중통신, 이미지 처리 기술이 선정되었다. 또한 기존 기술분류에 포함되지 않는 신기술 영역을 식별하였다. 여기에는 무인수상정 연구개발에 관련된 기술, 인공지능 기술, 유·무인체계와 협동 등 운용과 관련된 기술 그리고 진·회수 기술이 포함된다. 본 연구를 통해 파악된 기술 동향과 신기술 영역이 무인수상정과 관련된 핵심기술을 도출하고 연구개발 관련 정책 수립에 효과적으로 활용되기를 기대한다.
