Abstract : Physical description: 1 VHS video; col.; silent; 12 min.; 1/2 in cassette; playback SP. This report documents the results of a Small Business Innovative Research (SBIR-Phase II) project conducted for DARPA focusing on the use of all-source overhead remote sensor imagery for monitoring underground nuclear tests and related activities. This documentation includes: (1) the main unclassified body of the report; (2) a separate ground truth Annex; and (3) a separate classified Annex. Autometric's approach was to investigate the exploitation potential of the various sensors, especially the fusion of products from them in combination with each other and other available collateral data. This approach featured empirical analyses of multisensor/multispectral imagery and collateral data collected before, during, and after an actual underground nuclear test (named 'BEXAR'). Advanced softcopy digital image processing and hardcopy image interpretation techniques were investigated for the research. These included multispectral (Landsat, SPOT), hyperspectral, and subpixel analyses; stereoscopic and monoscopic information extraction; multisensor fusion processes; end-to-end exploitation workstation concept development; and innovative change detection methodologies. Conclusions and recommendations for further R&D and operational uses were provided: (1) the general areas of sensor capabilities, database management, collection management, and data processing, exploitation, and fusion; and (2) specific multispectral, hyperspectral, subpixel, three-dimensional modelling, and unique unconventional imaging sensor technology areas.
