A method of ground reflections reduction on the ground ranges

A method to increase the accuracy of antenna gain and radiation pattern measurements on far-field ground ranges is presented. The method consists in ground reflections reduction by means of proper range configuration depending on the pattern shape of the source antenna used. The main idea of the method assumes that the first null of the radiation pattern of the source antenna is directed toward the central point of the specular reflection zone. This results in a decrease in the illumination of the range surface and allows significant reduction of ground reflections.
