Abstract

The choice of nulling antenna type to be used for a given specification of user locations usually centers on whether to use a phased array antenna(PAA) or a multiple-beam antenna(MBA) for a satellite payload. This paper considers a MBA to analysis the nulling effect in the Korean peninsula jamming circumstance. First, the nulling performance and characteristics on the region of the earth coverage are confirmed with respect to the case of 7 beams. Then, optimum results are derived and compared to what can be accomplished with a fixed set of beams(the case of 10 and 19 beams are considered) for null steering to reject interference is investigated for a MBA.

일반적으로 위성에 탑재되어 재밍 신호 제거를 위해 널링 기능을 수행하는 안테나로 위상배열 안테나 또는 다중 빔 안테나를 사용한다. 본 논문에서는 다중 빔 안테나를 사용하여 한반도 지형에서의 널링 효과에 대하여 고찰하였다. 먼저 7개의 다중 빔으로 지구 전체를 커버하는 경우에 대하여 널링 성능과 그 특성을 확인하였으며, 다음으로 10개 및 19개의 다중 빔을 한반도에 적용하여 최적의 결과를 도출 및 비교하였다.
