Recent sea tests with a Variable Depth Source (VDS) (e.g. IUSW-21, LBVDS) have demonstrated increased submarine detection capabilities with a broadband active source that provide continuous active acoustic coverage below the layer and along the entire water column. The primary disadvantage of a VDS is the high impact that its launch and recovery system has on ship design. Advanced Acoustic Conce ...

An innovative integrated motor/propulsor (IMP) system is proposed that will improve the power density, efficiency and reduce acoustic signatures over existing designs. Gains in power density will be achieved by reducing the required motor torque in combination with motor structures that improve power density while working within the physical limits of the windings and magnetic materials.

With the achievement of 2.1 kW CW IR operation and an upgrade to 10 kW undergoing commissioning, free-electron lasers (FEL) are now a serious option for high-power, military and commercial applications. As specifically identified in the recent "Department of Defense Laser Master Plan", the key technology issue on the path to high-power FEL deployment is the demonstration of reliable, high-brightn ...

A definitive experimental study of cathode design and photoemissive materials for normal-conducting RF injectors is proposed. The University of Maryland (UMD) and Brookhaven National Laboratory (BNL) have agreed to collaborate with Advanced Energy Systems (AES) on this project. As an FFRDC, BNL will not receive any SBIR funding but has agreed to provide access to its existing facilities and equi ...

In support of low flying air vehicle missions, the Navy seeks improved capabilities to detect automatically, geo-locate, and determine the height above ground of vertical obstructions over operational areas. Of importance is the ability to assess the horizontal and vertical accuracy of detection results and detect obstructions above specified heights. The solution must be able to process and fuse ...

Aerosol particles play an important role in visibility, acid deposition, climate, and human health, although large uncertainties remain in quantifying their impacts which depend on their chemical composition and atmospheric transformations. An innovative aerosol mass spectrometer (AMS)has been recently designed to fill a critical need for size-resolved, quantitative chemical composition data on a ...

The proposed approach provides a high performance mechanical optical fiber splice of single piece construction. Leveraging on advanced glass and polymer material processing technologies, the new splice design offers advantageous attributes of compactness for use with minimum space intrusion, passive self-alignment of the fiber core in all directions, easy guided fiber insertion, quick action, a ...

Utilizing recently available exceptional mercurous chloride (Hg2Cl2) acousto-optic material having the largest known optical filter figure of merit, we propose to develop a state-of-the-art high speed and wide-bandwidth long-wavelength acousto-optic tunable filter (AOTF). The proposed device has the desirable performance attributes of wide operating wavelength range, low optical loss, low power c ...

This proposal addresses a novel photonic approach to the high performance IR scene generator. The revolutionary design has intrinsic advantages of broadband, high apparent temperature, compactness, high spatial resolution, low background temperature and noise, high reliability, and low cost, as compared with the competitive approaches. The device design overcomes the major shortcomings of the curr ...
