"WebA solution to the sidelobe problem is to apply a weighting across the rectangular pulse. This is common in FFTs, and tapering options in phased arrays are directly analogous to weighting applied in FFTs. The unfortunate drawback of weighting is that sidelobes are reduced at the expense of widening the main lobe. " - Design of error tolerance of a phased array
