Abstract
The Composite filter of Caulfield and Maloney, a linear combination of matched filters, is an optimum estimator in the mean-square sense. Composite filters may be made rotation invariant by using Circular harmonic filters as components. With a finite number of Circular harmonic filters, the output of the composite filter is invariant under rotation of the input only if all Circular harmonic filters have the same order.
