Abstract :
A simple method for accurately predicting the tracking sensitivity of a Cassegrain antenna having four peripheral horns grouped around a central `communication¿ feed is described. The technique utilises an analysis based on circular symmetry, similar to that ordinarily used to predict the antenna communication performance.
