Özet

In this letter, sideband radiation (SR) power has been investigated for nonuniform time modulated array (NTMA) systems. It is suggested that the SR calculations already studied in the literature need to be reviewed for NTMAs. From this point of view, a so-called prime-distributed time-modulated array that is a special kind of NTMA is introduced and a closed-form harmonic power expression is presented. Finally, it is shown that the former expression needs to be reconsidered for more appropriate results.
