Digital Sensor Simulation at the Defense Mapping Agency Aerospace Center,

The primary objective of the digital sensor simulation investigations being conducted at the Defense Mapping Agency Aerospace Center DMAAC is to establish an editing and analysis capability for digital culture and terrain data bases. These data bases are being produced by DMAAC to support advanced aircraft simulators by providing an improved low level radar training capability offered by digitally generated radar landmass images. As a result of the technology developed for aircraft simulator support, sensor guidance references scenes, visual, and microwave scenes are also being digitally generated. Currently, intensive studies are underway to generate synthetic input data bases with apparent resolutions finer than in the original data bases, using supportive data base information. Highly realistic sensor simulations have been generated, and the continuing emphasis is on modeling new sensors as well as improving resolution without increasing data base production costs. Author
