Abstract
A novel sideband radiation (SR) level suppression method for the time-modulated array (TMA) is proposed. By modulating their front-end RF switches with nonuniform periods, the SR level of the TMA can be remarkably suppressed, compared to using uniform periods. Numeric simulations are brought out to examine the performance of the proposed approach, and the comparison to the existing SR level suppression methods is provided. A simple S-band eight-element linear TMA is constructed and tested to verify its effectiveness.
