본 논문에서는 장비의 방사 방출을 현장에서 측정할 때 원치 않는 주변 간섭을 억제하기 위해 어레이 신호 처리와 적응형 잡음 제거를 결합하는 방법을 제시합니다. 먼저, 안테나 어레이에 의해 수신된 신호를 처리하여 메인 데이터 채널과 보조 데이터 채널을 형성한다. 메인 채널에는 테스트 중인 장비의 방사 방출과 감쇠된 주변 간섭이 포함됩니다. 보조 채널에는 감쇠된 주변 간섭만 포함됩니다. 그런 다음 적응형 잡음 제거 기술을 사용하여 주 채널과 보조 채널의 간섭 상관 관계를 기반으로 주변 간섭을 억제합니다. 제안된 방법은 가상 챔버 방법의 두 채널에서 주변 간섭이 상관되지 않는 문제를 극복하고 더 적은 어레이 요소를 사용하여 다중 소스 주변 소음을 억제합니다. 시뮬레이션 및 실험 결과를 통해 제안한 방법이 복잡한 전자기 환경에서 테스트 중인 장비의 방사 방출을 효과적으로 추출할 수 있음을 보여줍니다. 마지막으로, 주 채널의 빔 폭이 미치는 영향과 제안된 방법을 3차원 분포 신호로 일반화하는 방법에 대해 논의합니다.

Abstract: This paper presents a method combining array signal processing and adaptive noise cancellation to suppress unwanted ambient interferences in in situ measurement of radiated emissions of equipment. First, the signals received by the antenna array are processed to form a main data channel and an auxiliary data channel. The main channel contains the radiated emissions of the equipment under test and the attenuated ambient interferences. The auxiliary channel only contains the attenuated ambient interferences. Then, the adaptive noise cancellation technique is used to suppress the ambient interferences based on the correlation of the interferences in the main and auxiliary channels. The proposed method overcomes the problem that the ambient interferences in the two channels of the virtual chamber method are not correlated, and realizes the suppression of multi-source ambient noises in the use of fewer array elements. The results of simulation and experiment show that the proposed method can effectively extract radiated emissions of the equipment under test in complex electromagnetic environment. Finally, discussions on the effect of the beam width of the main channel and the generalization of the proposed method to three dimensionally distributed signals are addressed.
