Self-focusing array research model

A self-focusing array antenna model is described with a brief synopsis of an experimental program which was carried out to evaluate the technique and to demonstrate the principle by means of an operating model. The results of tests performed on linear and planar versions of the array are given in the form of field patterns. They show the successful operation of self-focusing in the presence of several factors including multiple targets, extended targets, moving targets and simulated atmospheric inhomogeneities.
