초록

최근의 우주개발기술 선진국들은 우주의 평화적 이용이라는 보편적 가치를 넘어서 자국의 이익을 극대화하기 위한 발판으로 우주의 전략적 활용에 더욱 더 집중하고 있으며, 조기경보 위성과 같이 지상에서 발사된 화염 정보를 이용하여 우주로 발사된 발사체의 실시간 감시와 궤적 추적 기능 등을 담당하는 위성들을 지속적으로 개발해 오고 있다. 본 연구에서는 이러한 조기경보 위성에서 발사체의 궤적을 실시간으로 추정할 수 있는 알고리즘을 진화연산이라는 인공지능 기법을 적용하여 제안하고, 이러한 비행 궤적 추정 알고리즘을 비행 궤적 추정 시스템의 시뮬레이터를 통하여 임의의 발사체 비행 궤적에 적용함으로써 제안된 방법의 성능과 특징을 입체적으로 확인하고자 한다.

The missile early-warning satellite systems have been developed and upgraded by some space-developed nations, under the inevitable trend that the space is more strongly considered as another battle field than before. As the key function of such a satellite-based early warning system, the prediction algorithm of the missile flight trajectory is studied in the paper. In particular, the evolution computation, receiving broad attention in the artificial intelligence area, is applied to the proposed prediction method so that the global optimum-like solution is found avoiding disadvantage of the previous non-linear optimization search tools. Moreover, using the prediction simulator of the launch vehicle flight trajectory which is newly developed in C# and Python, the paper verifies the performance and the feature of the proposed algorithm.
