Abstract
Recently, simulated annealing has been proposed as a suitable method for optimizing the weighting window of a linear array working under wide-band conditions. This paper introduces and discusses a new energy function that, minimized by simulated annealing, produces a beam pattern showing a flat side-lobe profile over a large interval.
