Low sidelobe nulling of sparse linear array using a hybrid method

This paper presents a hybrid method for the synthesis of sparse but symmetric linear array. Multiple constraints are taken into account for multiple objectives such as low sidelobe level (SLL), and nulling in specific directions. Two examples are presented and compared to those obtained by CLPSO, IWO/WDO and MCFO algorithms. Based on the comparisons, the proposed method gives a better suppression onto the sidelobe and interference.
