Weight functions for two-dimensional arrays using regularized deconvolution

A method for computing sidelobe-reducing weight matrices for planar non-uniform array geometries is described. These matrices are applied in the beam-space domain, are a function of frequency, and can be precomputed and stored for later use if the array geometry remains relatively fixed (they are signal-data independent). The method is based on the use of constrained, regularized deconvolution techniques to robustly reduce sidelobes and retain or improve the intrinsic angular resolution of the array.
