초록

평면 능동위상배열안테나 시스템에 있어, 간소화된 방사특성 측정 절차를 가지는 방사소자 결함진단 기법을 제시하였다. 이를 위해 평면 배열 구성에 대한 방사특성을 기반으로 선형 배열 구성으로 근사화 분석할 수 있는 방법 및 방사소자 결함진단과정에서 발생할 수 있는 유일해 문제를 해소하기 위한 방법을 연구하였다. 본 논문에서 제시된 기법 및 유전 알고리즘을 기반으로 다양한 평면 능동위상배열안테나 구성에 따른 방사소자 결함진단에 대한 모의실험을 수행하였다. 모의실험 결과, 제시된 방사소자 결함진단 기법은 다양한 구성을 가지는 평면 능동위상안테나에 대해서도 적용가능함을 확인하였다.

A radiating elements fault diagnosis method with simplified radiation pattern measurement procedure was presented for planar active phased array antenna system. For presenting the mentioned method, the technique for linear approximation based on the radiation characteristics of a planar array configuration and a technique for solving a unique solution problem that occur in process of diagnosing a fault in a radiating elements were presented. Based on the presented method and a genetic algorithm, experimental simulations were performed for radiating element defect diagnosis according to various planar active phased array antenna configurations. As a result, it was confirmed that the presented radiating element fault diagnosis method can be smoothly applied to planar active phased antennas having various configurations.
