Advanced Coherent Technologies, LLC has demonstrated the use of multi-channel imaging systems in a variety of
applications. These systems are composed of multiple cameras or 'channels', each of which can be coupled with spectral
filters, polarization analyzers, or unique optics (e.g. for field of view (FOV) or aperture adjustments). The channel
content is designed specifically for the extraction of information and/or the detection of targets. Airborne data collects
have been made over forest and maritime environments for the detection of various targets. The results of these collects
are discussed and analyzed. Of particular concern is how channel content is chosen in each environment and for each
target.

Radiance Technologies, Inc. has tested and demonstrated real-time collection and on-board processing of Multispectral
Imagery (MSI). Further, the test and demonstration consisted of a real-time downlink from the aircraft to the ground
station and real-time display of the processed data product. The multispectral imagery was collected with a low-cost,
low-profile MSI sensor, MANTIS-3T, from PAR Government Systems. The data product was created from output of a
novel spectral algorithm combination that increases the probability of detection and decreases the false alarm rates for
specific objects of interest. The display product was a compressed true color image in which the detected objects were
delineated with red pixels. A description of the end-to-end solution, issues encountered as well as their resolution, and
results will be discussed.
Radiance Technologies has developed and integrated a multispectral / hyperspectral data analysis toolbox into an easy to
use operator interface. HyperPACSTM (Hyperspectral data Processing Algorithm Comparison Software) allows the data
analyst to process spectral data in multiple input formats with many different spectral algorithms and/or different
algorithm parameters and options. Results are compared to user supplied ground truth, and Receiver Operating
Characteristic (ROC) curves providing a direct comparison of algorithm performance are generated. The HyperPACSTM
GUI makes the software easy to use, and the architecture readily allows for the integration of custom algorithms
provided by the analyst. Radiance has used HyperPACSTM in the evaluation of hyperspectral and multispectral
algorithms in support of an ongoing program. A description of HyperPACSTM, the GUI, and processing examples are
given.
