Minimum Resolvable Temperature Difference (MRTD) has long been used to describe the performance of thermal imaging systems. The Visibility Model II developed for second generation thermal imaging systems includes sampling and aliasing issues without

Proceedings of the Twenty-Seventh Southeastern Symposium on System Theory.
A new method for passive ranging based on the principle of triangulation is considered. The proposed orthogonal dual baseline scheme eliminates the well known "geometric dilution" effect, inherent in single baseline methods. The performance of each o

Conference Record of Thirty-Fifth Asilomar Conference on Signals, Systems and Computers (Cat.No.01CH37256).
A new virtual thermal image-processing model is introduced in this paper. This visualization program is based on earlier modeling work focused on predicting the minimum resolvable temperature difference (MRTD), which is a standard performance measure

Shore-based polarized infrared images of ship target and background were obtained in the MAPTIP measurement series, using vertical and horizontal polarization filters. These images have been analyzed to yield degree of polarization and polarization c

Targets and Backgrounds: Characterization and Representation.
Sea radiance in the mid and far infrared shows a considerable degree of polarization which affects observed target-to-background contrast. An improvement in contrast is achieved with horizontal (s-plane) polarization filtering to suppress sea surface

Realistic inversions of lidar signals for extinction using the Klett technique must take into account both the theoretical limitations of the inversion and the experimental constraints of the hardware. A simple test of the Klett inversion algorithm s

Characterization and Propagation of Sources and Backgrounds.
In previous papers we have presented measurements of degree of polarization in the mid and far infrared both in near-horizon sun-glint and in the adjacent sea background radiance. The polarization has been related to the Fresnel reflection and emissi

Measurements are reported of the infrared sunglint clutter channel caused by the direct solar reflection from the wave-perturbed sea surface at near-grazing angles of incidence. Apparent radiance has been measured over Monterey Bay as a function of a
