Signal signatures and signatures of various spectral decompositions of selected topographic features, such as line roads, road intersections, and rectangular buildings, were developed by using analog signal processing techniques. The signal signatures were constructed in the spatial domain, and the corresponding signatures of various spectral components were obtained in the Walsh transform domain. An electronic system for generating two-dimensional Walsh functions for decomposition of topographic features was designed and built. A scheme for detecting the decomposed spectral components using an analog processor was presented. Author
