参考场地法中参考值获取方法的研究

The Research of Reference Value Acquisition Method in Reference Site Method

验证了Anoop Adhyapak等人提出的参考场地法参考值的获取方法,发现该方法在3 m和5 m的测量距离下是有效的,但推广到10 m的测量距离时存在一些局限性。同时利用在中国计量科学研究院标准开阔场获取的不含地面反射的一组参考数据所构造的反卷积滤波器,在常规的EMC暗室中验证并复现了在3 m测量距离参考值的有效性,这将为暗室的期间核查提供一种新的方法。

The method for obtaining the reference value of reference site method proposed by Anoop Adhyapak et al.is verified,and it is found that the method is effective at the measurement distance of 3 m and 5 m,but there are some limitations when the method is extended to the measurement distance of 10 m.At the same time,a deconvolution filter is constructed based on a set of reference data obtained from the standard open field of National Institute of Metrology without ground reflection,and the validity of the reference value measured at 3 m is verified and reproduced in a conventional EMC anechoic chamber.This will provide a new method for the period check of anechoic chamber.
