✦ Synopsis

A numerical pattern synthesis technique for equispaced linear arrays that allows us to obtain shaped patterns with a specified sidelobe and ripple le¨el adhering to a desired array element excitation is described. The method perturbs the roots of the array factor in order to find the optimal sidelobe and null-filling topography of the pattern associated with a desired aperture distribution. Application to a shaped cosec 2 -pattern using a cosine-type amplitude distribution is presented.

## 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
