Abstract

The synthesis of time-modulated planar arrays for the design of monopulse antennas is addressed in this report. The sum beam is generated through an optimal set of static excitations and the difference beam is yielded by aggregating the array elements into sub-arrays suitably modulated in time by means of a set of radio-frequency (RF) switches. Towards this aim, iterative deterministic and hybrid approaches are proposed for the joint definition of the sub-array configuration and the pulse sequence controlling the RF switches to reproduce an optimal difference pattern at the working frequency, whereas minimizing the power losses in the harmonic radiation caused by the on-off switch commutations.
