The need to detect and locate individual landmines and minefields using man-portable or vehicle-mounted mine detectors is expected to continue, either as a stand-alone capability or a complement to remote detection. Casualties are common, yet minimal improvements to conventional mine detectors have been realized. This proposal introduces two new sensing capabilites that are complementary and hav ...

We propose to utilize photonic technology to produce high-power short-duration pulses for surface penetrating radar applications. The electromagnetic pulses are generated by using a PIN diode circuit which is biased at high voltage. The static electric energy stored across the diode junction capacitance can be discharged through illuminating the diode with an optical pulse produced by a diode la ...

Physical Sciences Inc. proposes a small arms scoring system based on a unique and innovative application of interferometry. The system is precise enough to satisfy the accuracy requirements of the Army Test and Evaluation Command and is immune from temperature and humidity effects. Any caliber munition from 22 caliber to >40 mm can be scored at velocities up to and exceeding 1550 m/s. In contra ...

Mine detection technology has not kept pace with the the advances in mine technology and the widespread proliferation of mine usage. The mine/minefield detection problem is complicated by numerous variables which. influence the process. Thus, solutions to problems such as the robust mine detection sensors and algorithms requires a fundamental understanding of information fusion as applied to aut ...

Automated surveillance techniques for target detection, classification, and identification are critically dependent on information processing based on mnltisensor integration. The full utilization of these various sensor modes requires the development of enhanced information processing algorithms. This proposal describes a novel algorithm for automatic target recognition (ATR) using both FLIR an ...

The new Phase Array Radars have range and angle resolutions capable of resolving multiple scattering centers of a single target. This capability produces multiple returns from a single target, creating a new problem for the tracking algorithms, viz. tracking a target that has multiple (resolved) scattering centers The solution proposed here is based on a Multiple Target Tracking (MTT) approach, ...

Frog Embryo Teratogenesis Assay: Xenopus (FETAX) is a 96-h, whole-embryo bioassay designed to detect potential developmental toxicants. The primary goal of this research is to improve the predictability and increase the overall utility of FETAX as a screen for developmental toxicants that pose a hazard to human health. Since Xenopus laevis embryos lack mixed-fliriction oxidase metabolism (cytoch ...

Unmanned Aerial Vehicles (UAVs) offer a lower risk and lower cost platform for the use of an Ultra Wide Band (UWE) Synthetic Aperture Radar (SAR) system for the detection of ground targets concealed by foliage. Given the size, weight, and power restrictions of a UAV, an impulse radar is an attractive radar system alternative because it offers a lighter and lower cost solution than a traditional c ...

We propose to design a model of visual target acquisition that can predict human performance in detecting low-contrast targets in complex scenes. This model will build on current state-of-the-art computational models of early human vision and visual search, and use proven cognitive modeling methods (belief networks for situation assessment and expert systems for knowledge-based reasoning) to mode ...

This Phase I effort proposes to prototype and demonstrate a Case-Based Reasoning Tool for Command and Control Warfare (C2W) Strategy Development. Our effort is motivated by the need to thoroughly understand and graphically depict vulnerabilities in the information battle space since Intelligence Preparation of the Battle Space (IPIBS) is the fundamental basis for successful execution of C2-attack ...
