Chemical/biological round discrimination using acoustic, seismic, and imaging data

The threat of chemical and biological weapons is a serious problem of current interest, as the ability to identify early whether an incoming artillery round contains high explosives or a chemical/biological agent provides the soldier with additional time to respond to the incoming threat. Traditionally, detectors specifically designed for that task have been used, however such detectors are expensive, and may not be always available when needed. We describe initial research work investigating such round discrimination by using and fusing information obtained from various acoustic, seismic, and imaging recordings obtained at different locations of the battlefield.
