Filtering environmental reflections in far-field antenna measurement in semi-anechoic chambers by an adaptive pattern strategy

摘要

A method to perform antenna far-field measurements in semi-anechoic chamber is presented. The method requires the measurement of the amplitude and phase of the pattern of the antenna under test in different spatial positions. The data are elaborated to estimate the direction of arrival of the reflected signals and to synthesize a receiving pattern with s in these directions. Experimental results confirm the effectiveness of the technique.
