A technique for the aperture partitioning

This paper presents a method for the partitioning of an aperture into sub-apertures preserving the performance. The technique represents a first stage towards a subarray synthesis and is based on a multi-stage approach wherein an aperture synthesis, an evolutionary algorithm, and, finally, a local search are adopted. A proper representation has been considered to reduce the number of the parameters defining the sub-aperture partitioning and simplify the use of a global optimizer.
