AbTech Corporation proposes to apply its unique abductive information modeling (AIMTM) technology to develop a sensor fusion demonstration for command, control, communication, computer and information systems. Phase I is the necessary and sufficient precursor to an operational disparate sensor fusion for C4I applications. Phase I will show the feasibility of using AIM to model sensor data, threats ...

We propose to develop and deliver a compact, high pulse repetition rate, mid-infrared optical parametric oscillator wavelength converter and cw fiber coupled diode pumped, Q-switched, Nd:YV04 diode pumped laser. A new nonlinear material, periodic poled Lithium Niobate (PPLN) enables an OPO to efficiently convert low energy pulses (150 microjoules) into the mid-infrared wavelengths. By changing t ...

With new detectors capable of sensing 7.5 - 9 micron wavelengths, a future threat is emerging since these detectors can be used in seekers. The need is to counter this threat with a laser source operating at 7.5 - 9 microns. The source requirements are 5 - 10 Watts of average power and a repetition rate of > 10 kHz. The proposed laser source is a Nd:YAG-pumped tandem OPO system consisting o ...

For future long-range theater ballistic missile defense, aircraft-mounted LADAR systems require eyesafe laser transmitters that produce higher pulse energy and better beam quality than currently available optical parametric oscillators (OPOs) pumped by diode-pumped Nd:YAG lasers. Aculight proposes a novel laser transmitter approach that can simultaneously generate the required pulse energy, b ...

AeroSoft, Inc. proposes to develop, incorporate and validate transition and anisotropic turbulence models for improving the low-Reynolds number predictions for high-lift airfoil configurations. The turbulence-modeling package will use Menter's two equati

The proposed prototype Operational Trainer for the FFG-7 AAW Combat System will provide the US Navy with a means for training the FFG-7 AAW combat team to operate their equipment in condition 1 watch stations. Each watch station will be provided with the ability to train as they fight by allowing continuous on-board AAW training that includes all elements of the combat system with interactions as ...

Attachment areas in the regions of rotating components of gas turbine engines degrade due to fretting wear and fatigue. Plasma sprayed coatings are often used to protect these regions. A thin, dense, Ti(C, N) composite coating based on sol-gel process is proposed. The simple, cost-effective sol-gel process will coat complex shapes and will provide superior performance against fretting wear. Di ...

The objective of the proposed Phase I work is to demonstrate the feasibility of using the Choi-Williams distribution to estimate the time ¿ frequency distribution of transients of interest to the IUSS. The specific objectives are to develop a metric for IUSS images and to show that the Choi-Williams distribution of these images may be used for classification. The Choi-Williams distribution is ...

The objective is to show that the performance requirements and costs of GPS/IMU implementations of attitude and sightline systems are substantially lower than those of conventional non- GPS aided designs. The errors of integrated GPS/IMU attitude and sightline stabilization systems are determined by simulations of these systems using complete mathematical models of IMUs and GPS receivers. The GPS ...

The growing reliance on wireless electronic systems presents us with a need for new diversity antennas for civilian and military platforms. These antennas must take account of platform curvature, material treatments and nearby interactions, all of which affect the antenna performance. To support the development and design of these antennas, a new generation of analysis is required which retains ...
