The technical objectives in this project consist of a research, development, and prototype roadmap for the successful implementation of the JTRS high power RF amplifier. The overall performance requirements of the JTRS high power amplifier under our proposal are as follows: Tunable Frequency Range: 400MHz - 2GHz Instantaneous Bandwidth: 30MHz Average Power: 150W Peak to Average Ratio (PAR ...

A conceptual Fischer-Tropsch (FT) based process is proposed for converting synthesis gas to C9 C16 hydrocarbons suitable for Navy use as synthetic JP5 fuel. We shall develop an advanced FT catalyst selective for C5-C8 olefins that will be subsequently dimerized to C10-C16; optionally, the process will include product upgrading, e.g., partial reduction. Phase I will investigate in parallel two cr ...

Networked Enhanced Automated Target Recognition (NEATR), is an important problem in modern network centric operations. This Phase I effort focuses on fusion in an embedded system with reasonable Size Weight and Power (SWAP). The proposed multi-layer approach provides novel detection and re-identification layers, target tracking and enhanced PCA-based recognition. The proposal presents a unique new ...

A novel non-contact approach is proposed for the direct measurement of mirror or antenna angular displacement in azimuth and elevation. This approach is uniquely suited for implementation in systems where the angular displacement is estimated or implied by an indirect method that has inherent error sources limiting the ultimate achievable accuracy. The error for the proposed measurement system ...

Biometrics in moving maritime environments presents some unique challenges. Even if the naval shipboard sensor is in a complex gimbaled mount for stabilization, the inherent motion of the smaller craft in which the subjects of interest are located means the system must deal with motion, potentially significant motion. The proposed work, will use FPGA-enhanced multi-mega-pixel imaging to address ...

Future Naval applications will require large pulses of electrical power for short time duration. NDI and it's university partner will conduct an investigation to determine the feasibility of developing a compact pulse generator to meet the Navy's need and include an assessment of cost and produceability.

As with all service branches within the Department of Defense (DoD), the mission objectives of the Navy are expanding to encompass not only major combat operations, but also asymmetric warfare scenarios. This expanding role requires the Navy to increasingly operate in littoral waters where effective identification of small craft and semi-submersibles is a critical capability for both fleet protect ...

Modern supersonic jet aircraft engines produce a high amplitude noise field with complicated characteristics due to turbulent behaviors of the hot jet. Researchers need better understanding of the turbulent structures in the jet plume to develop treatments to engines that might reduce the noise emissions. A significant obstacle to making these simulations practical and realistic for engine design ...

Non-invasive methods are required to measure the turbulence in supersonic jet plumes in 3-D with high temporal and spatial resolutions. The turbulent supersonic jet plume changes rapidly both in space and time, and hence any viable approach must acquire the entire 3-D velocity field at even faster speed for comparison with the temporal and spatial velocity field solved in Large Eddy Simulations. ...

Analysis of optical network performance provides key insights and enables comparison of technology and architecture alternatives beings considered for implementation of WDM LAN-based optical backbone networks within on-board aircraft platforms. Additional development of the models and algorithms used in commercial simulation and optimization tools is needed to characterize the complex interactions ...
