A method is presented which optimizes weights of general planar symmetric=20 arrays. It applies to full regular arrays as well as sparse arrays=20 with perturbed positions.=20

The objective is to find a weighting of the array elements which gives the minimum sidelobe level of the array pattern in a specified region - the stopband. The sidelobe level is controlled on a discrete set of points = from=20 this region. The method minimizes the Chebyshev norm of the sidelobe level.

The method is based on linear programming and is solved with the standard simplex method.=20 Examples of optimal weighted 1D and 2D planar arrays are presented.
