Design of scannable linear arrays with amplitude and phase optimisation for maximum side lobe level reduction

The design problem of scannable linear arrays is dealt with. This design of scannable linear arrays considers the optimisation of the amplitude and phase excitation across the antenna elements by using the well-known method of genetic algorithms (GAs). Simulation results for scannable linear arrays with the amplitude and phase excitation optimised by the GA are provided. Furthermore, in order to discover which design case could provide a better performance in side lobe level, a comparative analysis of the performance of the optimised design case with a conventional phased linear array is undertaken.
