Figure 37: Examples of Spatially Resolved Discrimination Results (the left and right columns<br />
are for release TD4043 and TD4063 (Bg), respectively) – A) includes the release details;<br />
B) indicates the plume map as a function of time and distance; C) indicates the<br />
spatially resolve discrimination results; D) summarizes the discrimination<br />
results. In both cases the plumes have been properly discriminated.<br />
The results utilize the spatial resolution capability of the WANDER system. With appropriate plume mapping<br />
and boundary selection the signal intensities can be integrated to enhance the system sensitivities while<br />
maintaining the ability to filter out hard targets or other artifacts. During full system operation the dynamic<br />
boundary selection ability extends the systems sensitivity to lower concentrations and more challenging<br />
environments.<br />

Unlike chemical warfare agents, biological warfare agent cross-sections, as well as simulants, are either<br />
entirely unknown or there is a paucity of information available. The problem is the complexity of bio-aerosol<br />
