Sidelobe Suppression by Phase-only Tapering with Integer Linear Programming

Phase-only tapering for sidelobe suppression is a simple method of phased array design due to the simplification of antenna manufacturing. When using digital phase shifters, considering the quantization of the phase, we employ integer linear programming to adjust the phased shifter and get a better pattern. The proposed method combines a fast sidelobe formula with a power reduction mathematical technique. Finally, we conduct numeric experiments to verify the proposed method.
