Robust Detection of Scatterable Minefields

The problem addressed in this proposal is the design and development of robust multi-sensor processing methods for detecting surface scatterable minefields from unmanned airborne vehicles (UAVs). Space Computer Corporation proposes to develop anddemonstrate a methodology for joint exploitation and fusion of minefield discriminants available from multiple image observables or features, and also from multiple wavebands or sensors. Phase I will emphasize the use of existing multi-band MidWaveInfrared (MWIR) and LWIR sensor data with a proven algorithm fusion technique to exploit spatial and spectral detection features within each individual waveband. SCC will apply band-to-band registration methods to the MWIR sensor data so that it may befully exploited for automated minefield detection. This effort will use an extensive set of processing tools and techniques, developed under DARPA funding for exploiting multispectral and multi-sensor image data. The Phase I Option will extend thisconcept by cross-registration of MWIR and LWIR sensor imagery to enable joint fusion of discrimination features between multiple sensors. In Phase II this general fusion framework could be expanded to accommodate other maturing sensor technologies formine detection including scanned lasers, pulse compression lasers (LADARs), and hyperspectral sensors operating in the reflective EO and thermal bands. The processing developed in this phase I effort, as well as the proposed Phase I option will establish amethodology and framework for the application of multi-algorithm, multi-sensor processing to the detection of scatterable minefields. This will advance the state-of-the-art in automated detection of scatterable minefields using existing sensortechnology. The processing methods developed will be useful across both DoD applications for tactical demining as well as humanitarian demining efforts. Commercial applications would include surveying previously war-torn regions for humanitariandemining purposes. Also, since many of the current and previously war-torn regions are also significant sources of natural resources we anticipate that there will be commercial interest in cost-effective surveying of regions for residual minefields.
