Abstract(in English)	When the radiation pattern of the antenna or the scattering pattern of radar cross-section is measuring, the characteristic is usually evaluated in the far-field area. In that case it is measured in the radio anechoic chamber to reduce unnecessary reflected wave and likely to deviate from the condition of the far-field according to the size or the measuring frequency. On the other hand, it is well known the method such as compact-range or the transformation processing method to the far-field from the near-field pick-up data. In this paper, it is reported on the expression and its measurement results when the idea of array factor (AF) is applied to the transformation of the near-field data acquired in the cylindrical scanning around under test device.
