In this paper, time-modulation is exploited for the synthesis of monopulse sub-arrayed antennas. The solution of the compromise sum-difference problem is obtained by setting the set of static excitations to an optimal sum set and synthesizing the “best compromise” difference pattern through a Continuous Partition Method (CPM) based approach. The array elements are aggregated into sub-arrays controlled by means of RF switches with optimized “on” time-durations. The switch-on instants of the pulse sequences are then computed by means of a particle swarm optimizer to reduce the interferences caused by the sideband radiations. A selected set of numerical results is reported to assess the potentialities of time-modulation in dealing with the synthesis problem at hand.
