Abstract

It is difficult to detect, track and intercept ballistic missile because of its high speed and short flight time from launching to target area. In order to increase the success rate of a ballistic missile interceptor, it is important to track the flight trajectory for a long time after the detection in the early launch. Radar Cross Section(RCS) of the target is important when the target to be detected by the radar, and the difference between the RCS value greatly changes depending on the viewing direction during the flight missile trajectory. In this paper, it is assumed that a ballistic missile is launched at east coast of North Korea, observe that missile by a land based radar and sea deployed radar. And it is analyzed and compared that RCS difference of ballistic missile.

탄도미사일은 속도가 빠르고 발사지점에서 목표지점까지 비행시간이 짧아 탐지/추적 및 요격에 많은 제한이 있다. 탄도미사일의 요격 성공률을 높이기 위해서는 발사 이후 조기에 발견하여 비행 항적을 오랫동안 추적하는 것이 중요하다. 레이더로 표적을 탐지할 때 중요한 파라미터는 표적의 Radar Cross Section(RCS) 인데, 탄도미사일이 비행하는 궤적 동안 관측 방향에 따라 RCS 값이 크게 변화한다. 본 논문에서는 북한 동해안에서 우리나라로 탄도미사일이 발사되었을 경우를 가정하여 육상 특정 지점에서와 동해상 특정 해역에 전개한 함정에서 각각 미사일을 관측하였을 때 미사일의 RCS 특성을 비교 분석 하였다.
