Bernstein polynomials are well known in the computer graphics community as the basis functions of Bézier curves. Like popular amplitude weighting functions such as Taylor weights, Bernstein polynomials are nonnegative and decay smoothly away from a single maximum. In this paper a modified Bernstein polynomial is introduced, defined with just four parameters for ease and speed of optimization. A particle swarm optimizer sets these four parameters to realize low sidelobe array amplitude distributions for a conformal array at various scan angles. This yields a novel method of generating realistic aperture weights, using the relatively new technique of particle swarm optimization.
