A phase-only power pattern synthesis technique for flat aperiodic arrays is presented. A convenient two-stage optimization procedure and proper representations of the unknowns of the problem mitigate the possible occurrence of suboptimal solutions. The use of a fast numerical algorithm using 2D Non-Uniform FFTs (NUFFTs) of NED (NonEquispaced Data) and NER (Non-Equispaced Results) types mitigate the computational burden. Design constraints on the element positions are also enforced to avoid overlapping as well as too large element spacings. The algorithm performance is analyzed against the case of a shaped-beam involving a typical China Oceania (Sinosat 1) coverage.

Abstract
A phase-only power pattern synthesis technique for flat aperiodic arrays is presented. A convenient two-stage optimization procedure and proper representations of the unknowns of the problem mitigate the possible occurrence of suboptimal solutions. The use of a fast numerical algorithm using 2D Non-Uniform FFTs (NUFFTs) of NED (NonEquispaced Data) and NER (Non-Equispaced Results) types mitigate the computational burden. Design constraints on the element positions are also enforced to avoid overlapping as well as too large element spacings. The algorithm performance is analyzed against the case of a shaped-beam involving a typical China Oceania (Sinosat 1) coverage.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
