Abstract

The reduction of the power losses in the sideband radiation of directive time-modulated linear arrays is addressed in this report. The approach is based on the optimization of the pulse sequence modulating the static excitations of the array elements to exploit pattern multiplication effects such that the sideband level of the harmonic pattern term related to the array factor is balanced by the element pattern distribution. A preliminary assessment is proposed in this report in order to show the effectiveness of the approach to suppress both the sideband level or the amount of sideband radiation.
