Organization and Manipulation of Infrared Scene Data and Infrared Modeling

摘要

This report documents the work performed by Teledyne Brown Engineering in the organization, classification, and manipulation of infrared scene data for the U.S. Army Missile Command (MICOM) Advanced Sensors Directorate. Software was developed for a PDP 11 computer with an on-line GRINNELL television imaging system to aid in classifying infrared scenes and extracting targets from such scenes. The storage and retrieval of the scene classifications was automated by the development of a data base and data base manager. The manipulation of the data included the calculation of power spectral densities and autocorrelation functions, the cross-correlation of targets with selected classes of background scenes, the application of a whitening filter based on the power spectral density of the background class, and the cross-correlation of two sensor FOV (field of view) models with the target scenes and background scenes.
