Neva Ridge Technologies proposes techniques to reduce the computational complexity associated with GOTCHA SAR processing through innovative improvements to the GOTCHA processor flow. The proposed approach treats the exploitation chain systemically. Specific improvements include the implementation of a fast back projection algorithm that combines SAR image formation steps with the co-generation o ...

Coherent and non-coherent change detection algorithms produced from SAR imagery have enormous intelligence value due to their sensitivity to change. But they are also difficult to interpret because of high false alarm rates and because of the basic statistical nature of SAR imagery which makes automatic filtering algorithms very difficult to robustly implement. This necessitates man-in-the-loop an ...

To provide complementary data and enable the synergistic gain from the fusion of multiple sensing modalities, there have been recent efforts to incorporate multiple sensors on the same platform. This approach may require vastly different detector material and apertures (optical lenses and antennas) due to the physics involved. However, within a limited spectral range (e.g., visible through infrare ...

Dismount discrimination is often based on static EO or IR target attributes such as height, length, and color. Various algorithms such as gait estimation have been developed to distinguish dismounts from other moving objects. Techniques that build high-fidelity 3D models of dismounts are fragile when applied to real imagery (i.e., video mounted on an unmanned aerial vehicle (UAV) with limited comm ...

Military operations in urban warfare provide an added emphasis to effectively detect, track, and ID ground targets in challenging environments.  Given the high dynamic nature of ground targets and the ambiguity that may result from closely spaced targets, incorporation of feature data from sensors such as hyperpsectral imagery (HSI) cameras provides a means to disambiguate the tracking of these t ...

The military tactics of our current environment—asymmetric warfare—demand effective targeting and intelligence, surveillance and reconnaissance (ISR). Target identification confidence can be greatly enhanced by interrogating and evaluating several, independent, target features. These include: surface reflectivity, surface type (metal vs. organic), target 3D structure, target 2D image and su ...

The major requirements for this program include the modeling of optical switching fabric technologies appropriate to space-borne systems at very high speed. Specifically, this program will evaluate two OptiComp candidate optical transceiver technologies against a Serial Rapid IO switching fabric. A down-selection to one optical transceiver technology will be made. Then, a simulation of that Serial ...

The major requirements for this program include the modeling of optical routing technologies appropriate to space-borne systems at very high speed. This program will investigate optical routing at speeds to from 3.125 ro 10 Gbps per channel, with a wavelength/channel density from 4 to 16 wavelengths. Models will be constructed for these regimes, and an experimental demonstration of an 8-wavelength ...

The proposed program will develop OptiComp''s coarse WDM transceiver manufacturing technology.  This WDM optical transceiver technology is highly novel, emphasizing manufacturability, ruggedization, modularity, ease of upgrade and qualification, extensive built-in diagnostic monitoring and test capabilities, as well as superior performance with reduced manfacturing complexity.  The modular desig ...

We have developed engineered epitaxial layers based on nanostructure technology that can be applied in hardening advanced deep submicron commercial silicon devices (90nm and smaller line width) against total dose degradation, single event upsets (SEU) and single event transients (SETs) by minimizing collected photocurrents (electron-hole pairs) via recombination centers.   This could provide an ...
