In this work, a new idea about the sideband radiation (SR) of nonuniform time modulated Arrays (NTMA) is introduced. The calculations of the uniform systems have been studied in the literature and it is suggested that the same equations are valid for the nonuniform systems too. However, the idea that calculations should be different has been the main motivation source for this study. In order to simplify the system and obtain the calculation simplicity, a prime coefficient distribution is suggested and the power equation is derived from the fundamental equations. As a result, it is concluded that the solution of the nonuniform systems is different from the uniform one and the general opinion in the literature should be reviewed.
