Application of a Conjugate Gradient Method to the Synthesis of Phase-Only Planar Arrays

Abstract

The problem of minimizing the peak sidelobe level of a planar array of dipoles using phase-only synthesis is investigated. A hybrid nonlinear function minimization scheme is developed using a Taylor series approximation and a conjugate gradient algorithm. A weighted average peak sidelobe level function is introduced to yield a more stable numerical procedure. The peak sidelobe level is found to decrease in proportion to the logarithm of the aperture behavior.
