Abstract

The invention provides a field sensor calibration system and a method, and the problems of a small calibration area and large influence on field distribution by a field sensor are solved. The field sensor calibration system comprises a single cone body and a flat plane body, and a single cone body antenna is formed. The single cone body is gradually narrowed from a top surface to a bottom surface, and the rotation curve shape of a side face is an exponential curve. According to the field sensor calibration method, firstly the single cone body antenna is set and is gradually narrowed from the top surface to the bottom surface, thus the space area used by the field sensor calibration is enlarged; a cube calibration area is defined in the range of single cone body antenna radiation, the vertex and each side middle point of the cube are provided with reference points, the electric field intensities of each reference point in the conditions with the field sensor and without the field sensor are calculated and compared, and the influence of the field sensor on the field distribution in the calibration area is obtained. The single cone body antenna impedance transformation method of the present invention is in the form of exponential transform, and the calibration precision of the field sensor is improved.

Description

technical field [0001] The invention relates to the field of electromagnetic field testing, in particular to a field sensor calibration system and method. Background technique [0002] At present, electromagnetic pulse field sensors are generally used for the measurement of pulsed fields at home and abroad. The pulse rise time and duration of ultra-broadband short-pulse electromagnetic fields are on the order of ns or shorter, and the spectrum width coverage is tens of MHz or wider, so it is difficult to measure. In order to ensure the accuracy of the electromagnetic pulse field strength measurement, it is necessary to perform performance calibration on the electromagnetic pulse field sensor in the time domain. [0003] The difficulty of time-domain calibration is to obtain the known field of the time-domain pulse field, that is, the standard field. The electromagnetic field sensor and probe calibration standard IEEE Std1309-2005 provides a field sensor calibration system ...
