Paper Abstract

This paper discusses quadratic filters for distortion invariant pattern recognition. Quadratic filters are easily implemented in coherent optical correlators and are shown to improve clutter rejection. Issues relevant to the design and performance of these filters are discussed and an optimal filter design is derived.
