Phase-Only Control of Peak Sidelobe Level and Pattern Nulls Using Iterative Phase Perturbations

Minimization of the maximum sidelobe level for a given array geometry, amplitude distribution, and nulling sectors by phase-only adjustment of the element coefficients is studied. Nonlinear optimization problem for phase distribution is solved using a novel iterative convex optimization algorithm, w...
