Abstract

Being inspired by the time modulated technology, an approach for synthesizing linear thinned array with low sidelobe level (SLL) is presented. In the proposed method, the thinned array is obtained through replacing the static element weighting by the time duration of a prescribed modulation cycle, and the iterative Fourier technique (IFT) is performed to explore low sidelobe array. Furthermore, for the un-neglected higher sideband level (SBL) of the harmonics, the algorithm of differential evolution (DE) is adopted to lower the SBL through optimizing the on-off time of time modulated elements. Numerical instances validate that the obtained thinned array has considerable reduced sidelobe level as well as reduced SBL, as is compared to the conventional thinned array.
