Visibuilding
Abstract
The Visibuilding program is developing technologies and systems for new building surveillance capabilities to detect personnel within buildings, determine building layouts, and locate weapons caches within buildings. This program is developing techniques to inject and recover probing radar waveforms and unravel the complicated multipath in the return signals to enable the mapping and characterization of building interiors. Radar signals are being used to image static structures directly. Doppler processing of radar signals is also being exploited to find, identify, and perform feature-aided tracking of moving personnel within a building and allow mapping of building pathways and stairways by monitoring traffic through buildings. Multipath and propagation effects are modeled and iteratively compared with hypotheses of building structures to provide 3-D building maps and large concentrations of metal materials like weapons. Other sensing modalities and component technologies are concurrently being investigated that offer the possibility of providing complementary information about the layout of large buildings as well as their associated underground areas. Component pieces will transition to the Army's Program Executive Office (PEO) Intelligence, Electronic Warfare & Sensors (IEWS) and U.S. Special Operations Command.
