The subset of Elements used to form an independent sub beam of a Phased Array Radar Antenna can be found using a two stage Genetic Algorithm. The use of Pareto optimisation allows the determination of the minimum set of Elements to be used for the desired beam pattern. The outer GA optimises the selection of elements to be used in the sub beam, while the inner GA optimises the tuning parameters of the selected set of elements.
