Paper Abstract

The application of Lockheed's phase correlation image matching technique to missile guidance has been sys-tematically investigated during the past several years. An effective approach to the scene distortion problem has been developed and verified for a variety of sensor types by computer simulation. The method involves the computation of a full bandwidth Fourier phase difference matrix for the reference and sensed scenes to be matched, followed by the application of the inverse Fourier transform to the phase matrix modified by a series of bandwidth-reducing filters to produce a set of trial correlation functions. The "best" matchpoint is then selected using parameters derived from each correlation function. A novel method for onboard reference map storage has been developed using quantized Fourier phase angles.
