Comparison of antenna beam patterns obtained from near-field test measurements and ground target scans
Abstract
The measured antenna beam pattern of a radio tower target was compared with the antenna beam pattern of a planar near field antenna, in order to determine the suitability of planar antennas for meteorological applications. The azimuthal and elevation cuts of the two beam patterns are reproduced in a graph, and their characteristic features are compared. On the basis of the comparative results, it is concluded that a ground target provides an adequate beam pattern in angular positions of the sidelobe, as long as the returned signal is above the detachable background from clear-air return, or the minimum detectable signal of the receiver.
