The ability of either a human observer or an automated sensor to recognize a target in an infrared scene depends both on the target and clutter content of the infrared scene. Metrics have been developed to quantify the difference between the target and its background, to be used as independent variables in the modeling of both observer performance and of automated seeker performance. We believe ...

Here OptiMetrics Inc. proposes to develop an Information Architecture for the simulation of intelligence information, processes and sensors that are the components of C3I systems. That Information Architecture (IA) builds on the concepts of High Level Architecture (HLA) for DIS. It would provide the logical structure for the integration of existing and future intelligence simulations and for eva ...

3-D visualization of multiple RF fields requires innovative display techniques to overcome a number of technical challenges, including surface polygon reduction for increased graphics speed, and discrimination of multiple overlapping surfaces. The innovation in the present proposal derives from the PI's recent development of a 3-D tactical display for the Navy in which the interaction of sonar ac ...

Q-DOT proposes to develop a 1-dimensional receiver array for the unique laser radar (LADAR) system developed at the Army Research Laboratory. The primary elements of this new system include an amplitude modulated solid state laser transmitter and an incoherent optical receiver array. Each receiver channel employs an avalanche photodiode (APD) optical sensor that exhibits significant multiplicati ...

RIA scientists have developed a numerical scheme for the detection and classification of complicated signals in highly noisy environments (negative SNR). This method performs DIC using nonlinear signal information based on techniques developed from the theory of Chaotic dynamics. Preliminary tests on real-world data sets, recently supplied by Navy personnel, indicate that this method will likely ...

The current market for fast switching frequency sythesizers is growing rapidly. Most synthesizers available today will not meet the stringent requirements for switching quickly, providing spectrally pure RF outputs and minimizing physical size and cost. As part of a current SBIR program, S.T. Research has developed a wideband, fast switching synthesizer, based on the use of broadband phase-locke ...

Clutter metrics we important image measures for evaluating the expected perfomance of sensors and detection algorithms. Typically, clutter metrics attempt to measure the degree in which background objects resemble targets. That is, the more Target-like objects in the background the higher the clutter level. However, it is critically important that the effects that the sensor system and the oper ...

High-speed large-format solid state imaging devices have been used for several years in a variety of scientific, industrial, and consumer applications. As the format size increases, however, the problem of post-capture processing becomes significantly larger, not only in terms of raw memory required but also in terms of processor throughput. Ideally, an imager capable of performing significant p ...

Digital imaging has become more widespread with the advent of digital video and still cameras, Special effects using digital compositing techniques, and advanced optical processing applications. With this spread of digital imaging has come a requirement for higher-resolution systems capable of competing with standard halide film technologies. It has been estimated that a typical 35mm.modern colo ...

General aviation and commuter aircraft generally do not have adequate deicing equipment to operate safely in all types of icing conditions. Since icing forecasts are not yet sufficiently reliable for pilots to avoid icing conditions, an airborne system that remotely detects icing conditions ahead of the aircraft could prevent serious accidents. The National Oceanic and Atrmospheric Administratio ...
