FINDING DEFECTIVE ELEMENTS IN PLANAR ARRAYS USING GENETIC ALGORITHMS

By J. A. Rodriguez, F. Ares, H. Palacios, and J. Vassal'lo

Full Article PDF (325 KB)

Abstract:
A technique that allows to locate defective elements in planar arrays by using some samples of the degraded far-field power pattern is described. This approach uses genetic algorithms to minimize the square of the difference between the far-field power pattern obtained for a given configuration of failed elements and the measured one. The method also allows to detect defective elements that don't fail completely
