초록

일반적으로 저피탐(Low Probability of Intercept, LPI) 레이더는 펄스레이더에 비해 매우 낮은 송신출력, 높은 안테나 이득 등으로 인해 상대방의 전자전 장비(Electronic Warfare Support, ES)에 탐지될 확률이 낮다. LPI 레이더는 RCS 감소 설계와 같이 전자파에 대한 스텔스 기법의 한 종류로, 궁극적인 목적은 상대방에게 탐지되는 거리를 줄이는 것이며 RCS 값, LPI 성능 중 한 가지라도 성능이 미흡하면 적보다 먼저 탐지되게 된다. 본 논문에서는 LPI 탑재 플랫폼의 피탐 확률 감소를 위해 고려해야할 사항을 제시하였다.

In General, LPI radar's detection probability by ES equipments is lower than that of conventional pulsed radar because of very low transmitting power and high antenna gain etc. LPI radar is a kind of RF stealth technique such as RCS reduction design. Therefore the ultimate goal of LPI radar is detection probability reduction by opponent. If one of the two, RCS value or LPI radar performance is not sufficient, own platform will be found first by opponent. In this paper, some considerations are suggested for detection probability reduction.
