ABSTRACT:In this paper, time modulation is applied to a small number of elements of a linear array that radiates either sum or difference patterns, in order to take control over their sidelobe levels. The simulated annealing (SA) technique helps to obtain the optimum time pulses applied to such elements in terms of sideband minimization.

We describe the use of simulated annealing to synthesize multiple‐pattern linear antenna arrays with fixed amplitude distributions, and we present examples of two types of a two‐pattern array. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 26: 52–53, 2000.
