근전계 빔 집속 시험 기법을 활용한 평면위상배열레이다 시스템 복사 및 빔 조향 특성 검증 = Verification of Radiation and Beam-Steering Characteristics for Planar-Phased Array Radars Using Near-Field Beam Focusing

다국어 초록 (Multilingual Abstract)

In this study, we propose a verification method for a planar-phased array radar system using a near-field beam focusing(NFBF) test method. We then confirmed the validity of the results. The proposed method can be used to verify a radar system in the near-field range of twice the antenna aperture size, and this is done in the same manner as the field system performance test conducted in a non-outdoor electromagnetic anechoic chamber. The test configuration and procedure for verifying the NFBF using near-field energies were reviewed. In addition, the phase compensation values of additional individual channels were quantified through mathematical verification of the beam-steered NFBF test. Based on a theoretical verification, the actual NFBF test was performed and the validity of the test method was confirmed through comparison with ideal analytical results.
