With the advances in solid-state electronics and optoelectronics, ultra wideband radio frequency receiver designs are now practical. One of the consequences of these large bandwidth waveforms is the very high range resolution that results. Various architectures of receivers have been proposed for the ultra wideband applications, but most popular architectures among them are heterodyne, homodyne, l ...

The primary objective of this program is the investigation of new approaches to achieve well-dispersed ultrahigh loading of carbon nanotubes (CNTs) in structural resins for advanced composites. “Well-dispersed” means CNTs that are optimally dispersed for achieving desired properties like strength, modulus, toughness, and thermal conductivity, rather than uniformly dispersed CNTs. Phase I will ...

Photonic links and networks offer numerous advantages to analog RF systems including inherent wide bandwidths, a harness exhibiting a reduced size, weight and improved flexibility, and nearly lossless signal. Current all-electronic delay line systems based on microwave components suffer from high signal loss and dispersion as well as large size and weight. An efficient way to achieve true-time-del ...

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 build on the success of Phase 1 to develop a system us ...

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 ...

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 ...

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 ...

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.

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 ...

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 ...
