Auto-Correlation of Elevation Data Form Digital Stereo Imagery
Abstract
This is the final report that describes the option period for this contract. During this option, we participated in a competition between various vendors to generate the best digital target map for the proposed sensor. To the best of our knowledge, this sensor is a coherent radar with improved range resolution that enables it to detect fine elevation differences in the terrain and to compare them with a stored elevation signature of the area upon target approach. Although our algorithms are in their infancy, we accepted the challenge and will attempt to produce an appropriate elevation signature description using the data supplied. A series of tools were created to exploit the DPPDB product and display the processing results. A subset of this toolset enables the viewing and exploitation of the correlation results that were generated. The toolset allows for investigation of various tuning parameters and settings to provide insight into the appropriate threshold values necessary to extract the desired features. This entire process is automated. After the thresholds are determined, the entire DEM was generated by the algorithms and stored on the computer. No human interaction was performed during its creation.
