SYNTHESIS OF SHAPED RADIATION-PATTERNS USING AN ITERATIVE METHOD

Radiation patterns with a prescribed shape are useful for many applica tions. In this paper an iterative algorithm is presented for obtaining a set of excitation coefficients of a linear array that generates a d esired main lobe shape with an arbitrarily suppressed sidelobe level. This technique can be applied to linear arrays with uniform or nonunif orm spacing and isotropic or nonisotropic elements. The design example s presented show that the iterative algorithm converges rapidly to the desired solution.
