%X In this report, the simultaneous control of both instantaneous and average features of the TMAs patterns generated at the frequency of the receiving signal just exploiting the available time-based DoFs is investigated. The directivity of the main beam has been kept constant within the modulation period by means of the joint optimisation of both pulse-sequence descriptors (i.e., ‘switch-on times’ and ‘switch-on instants’) in order to avoid undesired fluctuation of the energy delivered at the receiver, which cause a non-negligible waste of the desired signal power in the SR, while synthesising a desired average pattern at the working frequency.
