In this paper, an innovative approach for the reduction of the sideband level in time-modulated linear array has been presented. First, the proposed strategy has been mathematically justified showing that the SBL can be lowered by modifying the switch-on instants. Accordingly, a PSO has been used to minimize a suitable cost function quantifying the mismatch between the actual pattern features and the desired ones. Preliminary results have show that such a technique effectively works and it turns out to be a suitable methodological approach to the optimization of the performances of time-modulated arrays.
