초록

본 논문은 최근에 CISPR(국제전자파장해특별위원회) 에서 논의되고 있는 전자파 장해 측정용 야외시험장과 전자파내성 시험장과의 상관관계에 대한 것이다. 먼저 OATS와 FAR에 대한 상관계수 이론치를 도출하였으며, 각 시험장에서 3 m 거리에 대한 비교 측정을 하였다. 상관관계에 대한 이론치를 프로그램화 하였고 시험장에서 측정한 값과 비교를 하였다. 30 - l,000 MHz 에서는 6 dB 이내의 이론값과 실험값의 차이값이 나타나고 있어 FAR시험장이 OATS시험장의 EMI(전자파방사) 대체 시험장으로 활용될 수 있음을 확인하였다.

This study is based on the recent CISPR research which is focused on correlation of OATS and FAR. First, we calculate the correlaton factor about OATS and FAR. We measured the field strengths at the OATS and in the FAR both for 3 m distances to obtain the experimental correlation factors. We programmed correlation factor that calculated from theoretical models. The Results showed the measured correlation factor in 6 dB from 30 to 1,000 MHz. It will be use to substitute FAR for OATS about efficient to measure EMI(Electro Magnetic Interference).
