Abstract :
A new approach to producing low sideband pattern levels in time-modulated linear arrays is presented. The technique uses a switching sequence which is time-symmetric within the switching period. Numerical examples are presented to compare the proposed approach to conventional switching schemes for a 16 element linear array with predefined −30dB Taylor weights.
