Multi-channel array manifolds are required for wideband AESA applications. In modern solid-state AESA arrays, MMIC-based T/R modules generally utilize digitally-controlled phased shifters to steer the beam on transmit and receive. The given phase value is only accurate at one frequency, and so for wide bandwidths of several hundred MHz (at X-band for example), the beam does not get formed properly ...

Key obstacles to extending OFDM to wireless links and networks at high-frequencies and dynamic channels are inherent low performance to Doppler and power amplifiers operation with high back-off. Other significant obstacles are multipath and impulsive noise. PEARL-OFDM combines a layered architecture with technologies that mitigate such obstacles and enable full-range rates that maximizes connectiv ...

The proposed JP-8 powered cooling technology was co-invented by ThermAvant Technologies, LLC and the University of Columbia-Missouri (MU). The technology is based on the ejector cooling cycle and has the following unique features: thermodynamically and fluid dynamically optimal working fluids for increased high heat transfer and reduced entropy generation; low-shock loss, momentum conserving eject ...

A cooling system that converts waste heat from power supply units into useful space cooling is sought by the U.S. Army to reduce the electrical loads and fuel consumption in mobile military platforms. Unfortunately, conventional heat actuated systems are too large and inefficient. ThermAvant Technologies has developed a thermally-driven cooling system that combines environmentally benign fluids wi ...

This Phase I STTR effort develops and tests spectropolarimetric surface characterization algorithms for LADAR based remote sensing. A systematic approach is used which first defines the operational scenarios for which the algorithms are to work. These scenarios are then used to define requirements for LADAR hardware and algorithms which serves to focus the algorithm development effort. A librar ...

The design and development of piezocrystal sonar transducers is a challenging multidisciplinary and technological effort that spans many fields and skill sets. We look to extend and improve our transducer assembly technologies to reduce cost and implementation time for sonar technology transition and in particular our methods for Active-Passive single crystal ring development and fiber glass wrapp ...

In order to improve the safety and efficiency of navy high speed small boat operations, FarSounder proposes a 3-dimensional, forward looking sonar solution capable of simultaneous bathymetry sensing and obstacle detection out to ranges of at least 1640 ft (500m). Additionally, the system will be cable of 50 knot operation and suitable for installation on a high speed planing vessel such as common ...

Prediction of the noise from impinging turbulent, hot, supersonic jets from real flight systems in an operational environment is an extremely challenging problem. The broad ranges of both temporal and spatial scales that affect the results make a conventional large eddy simulation impractical. To address this issue, a technique is proposed which makes use of localized high-fidelity simulations, wh ...

Innovative Technology Applications Company (ITAC), LLC, in partnership with the University of Notre Dame (ND), propose to develop an advanced plasma-enhanced aerodynamic control (PEAC) technology to significantly enhance the performance of vertical takeoff and landing aircraft, in particular the V-22 Osprey tiltrotor vehicle. Innovative open- and closed-loop PEAC concepts will be designed to incre ...

The proposed BIOFOILS program will develop innovative designs and control concepts for bioinspired hydrofoils for use in future Naval undersea vessels. The program will incorporate novel structures and mechanisms inspired from aquatic mammals into the design and function of human-engineered biofoils. In Phase I, Innovative Technology Applications Company (ITAC), LLC and its collaborators will expl ...
