Abstract:

This report describes the development of a Digital Modular Change Detector DMCD. One method of Interpretation of Synthetic Aperture Side-Looking Airborne Radar SLAR images is based on the comparative analysis of two images of the same area exposed at Different times to detect any differences or changes in detail that have occurred during the interim period. Recent improvements in SLAR technology have advanced the operational state-of-the-art in collection system where radar imaged data can be obtained over wide swath widths at rates of many thousand of square nautical miles per hour. To exploitate intelligence in a timely manner from this data requires on-line automated processing, screening, and display of changes pertinent to an interpreter. This program designed, fabricated, tested and demonstrated a digital modular change detection system for SLAR imagery. The modular approach uses a programmable module, provides the capability for system growth potential and adaptability to meet new Air Force SLAR imagery processing requirements. Author
