Pixel-Level Fuzzy-Logic Image-Processing Applied to Range-Only-Radar Signals

摘要

This report documents work in progress on fuzzy expert systems. Pixel-level fuzzy-logic image-processing (PIXLFLIP) uses fuzzy logic on subwindows centered on each pixel of an image to determine the processing or filtering associated with the center pixel of the subwindow. Here, the PIXLFLIP is applied to enhance range-only-radar (ROR) profiles that have been stacked to produce an image chip. Because the profiles have been aligned by previous processing, the line enhancement needs only to consider vertical lines. The fuzzy, rule-based filtering not only enhances the strong consistent signals, but also suppresses the clutter forming the background. This approach offers significant potential. Further investigation is recommended.
