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.
PAR Government Systems Corporation (PAR) with Advanced Coherent Technologies, LLC (ACT) has developed
affordable, narrow-band polarimetry sensor hardware and software based upon the PAR Mission Adaptable Narrowband
Tunable Imaging Sensor (MANTIS). The sensor has been deployed in multiple environments. Polarimetric imagery of
the clear blue sky and the sea surface has been collected. In addition, a significant amount of calibration data has been
collected to correctly calibrate the sensor for real-time Stokes Vector imaging. Data collected with the MANTIS
polarization sensor has been compared to modeled data. The sensor hardware and software is described and some
representative collected calibration data are presented and compared to a developing model.
