Abstract:

The effects on the radiation pattern when N pairs of sym etrically located radiators are removed at random from a large 2No 1-element linear array are studied as a stati tical problem. It was possible to determine the limiting bounds of the radiation pattern the probability that the main-lobe beamwidth is widened by not more than a given percentage the prob bility that a certain side lobe does not deteriorate by a specified amount and the probability that all side lobes are below a specified level. The general analysis is valid for arrays with an arbitrary amplitude distribution which is symmetrical with respect to the center element and with an arbitrary progressive phase shift. Curves showing computed statistical data for a 201-element array with both the uniform and a cosine-squared amplitude distribution are presented. Author
