Title: Fusion of Information from Optical, Thermal, Multispectral Imagery and Geologic/Topographic Products to Detect Underground Detonations. Annex 1 - Ground Truth report. Phase 2. Final report, 8 Nov 91-25 Feb 92

Abstract

The project is entitled Fusion of Information from Optical, Thermal, Imagery and Geologic/Topographic Products to Detect Underground Detonations. The study established the feasibility of using such data to support the detection and monitoring of underground tests. The second phase of the study brings the analyses into the real world by testing the feasibility against a real underground test, recommends the suite of sensors to be used and the tools to exploit them. The current task involves the selection of an ongoing underground nuclear test, the scheduling of overhead imagery and the analysis of both the collected imagery and collateral data. A significant portion of this task is the compilation of a Ground Truth document that provides an historical background of the test and the changes that occurred. This report provides data that can and will be used to support the development of special digital tools that may be employed with multispectral data collected by various civil sensors. Documentation of ground truth before and after the test detonation, provides data on the visible changes that have occurred which should become the focal point for developing analytical tools to record the existence of an underground test.

  • This report focuses 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 imagemore » 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 RD and operational uses were provided in: (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 modeling, and unique unconventional imaging sensor technology areas.« less
  • As the nuclear family of countries continues to expand, the need for close monitoring of worldwide test activities becomes an intriguing technical challenge. Phase I of this study focuses on those unclassified and classified imaging sensor products that can now, or may soon, be brought to bear on the monitoring problem in order to determine the feasibility of using such data to supplement or answer specific requirements. Since the products may be acquired on hardcopy (film) or softcopy (digital tapes), means to integrate them were investigated. This required that the digitizing of film and paper products be analyzed in termsmore » of timeliness and fidelity as well as means to reproduce the derived digital results on high quality hardcopy. Several imaging sensor products were analyzed independently and jointly to document their unique characteristics and to assess their utility for supporting nuclear test monitoring. Those techniques that showed considerable promise were the precise superpositioning of data from multiple sources, the stereoscopic viewing of multiple mission and sensor products, and three-dimensional mapping of multiple image sets.« less

  • This contract studied experimentally and theoretically the fundamental limit in the modulation bandwidth of quantum well lasers. The motivation of this study arises from the fact that, despite numerous predictions in the last few years on the potential superiority of quantum well lasers in high speed modulation, none of them have been successfully verified experimentally. The initial approach was to study gain compression as a fundamental mechanism of limiting modulation bandwidths of quantum well lasers. To the extent that the physics behind gain compression was not known, a major effort was put in uncovering the fundamental physics responsible for gainmore » compression. It was subsequently discovered that the finite carrier capture time into the quantum well, despite being a very fast process (1 ps or less), can lead to a large gain compression parameter. We have then proceeded along this line and studied the fundamental quantum capture of electrons and holes into quantum wells, as well as the consequence of these capture processes in the modulation dynamics of quantum well lasers. The goal here is not only to understand what limits the modulation bandwidth of quantum well lasers, but to make use of that knowledge to design suitable structures for overcoming these limitations. The following sections contain detailed descriptions of the experimental and theoretical work that uncovered the above facts.« less
