THE NAVY-S ASW DETECTION AND CLASSIFICATION SYSTEMS ARE DEPENDING INCREASINGLY ON THE USE OF TOWED RECEIVING ARRAYS BECAUSE THEY PROVIDETHE OPPORTUNITY TO OBTAIN A LARGER MOBILE RECEIVE APERTURE WITH LESSFLOW NOISE THAN OCCURS WITH HULL MOUNTED ARRAYS. UNFORTUNATELY, ALONG WITH THE ADVANTAGES OF A TOWED ARRAY COME INHERENT PROBLEMS. THE MAIN PROBLEM IS THAT THE ARRAY CONFIGURATION CHANGES WITH TIM ...

The overall objective of the proposed research is to develop bistatic detection techniques for shallow water near land warfare operations. The focus of our proposed research is to achieve detection enhancement in environments characterized by dense multipath through application of optimal detection theory coupled with accurate acoustic modeling. The first specific objective is to consider alternat ...

Significant savings in system life cycle costs can be realized when common Automated Test Systems (ATS) resources are used to meet both system production and field maintenance needs. Additional cost avoidance and quality gains are the result of transferring unit under test (UUT) design data, "lessons learned" gained during manufacturing in-process and system acceptance (sell-off) testing to the ma ...

AN INNOVATIVE SINGLE ANTENNA ARRAY IS PROPOSED WHICH CAN ACHIEVE EXTREMELY HIGH DIRECTION OF ARRIVAL ACCURACY FOR PULSE SORTING APPLICATIONS. THE MAXIMUM DIAMETER IS LESS THAN 4 INCHES AND CAN BE MADE FLUSH MOUNTING.

We propose to conduct a comprehensive feasiblity and assessment study for relevant Navy canopy ejection simulations using an advanced unstructured grid flow solver. The results of the Phase I study will be sued to guide and enhance the development of acomprehensive interactive canopy ejection simulation capability for Navy applications. The study will be conducted to show the feasibility, accura ...

A new generation of motion systems which are software-driven leads to the possibility of far more compact, adaptable, and reliable designs for multipurpose motion-based training simulators. An important consequence of this new technology is that it may no longer be necessary to make a once-and-for-all decision to include, or exclude, a motion system from a particular training device. Now we may be ...

Currently, airbreathing propulsion systems which operate in the subsonic to high supersonic regime are expensive, complex and heavy. To overcome these limitations, a novel propulsion concept based on a liquid hydrocarbon-fueled Pulse Detonation Engine (PDE) is proposed. The innovation draws from recent successes in computational fluid dynamics and from several engineering studies and PDE develop ...

Phoenix Integration, Inc. proposes a 6 month design and feasibility study to investigate application of innovative software techniques toward an integrated program for the design and analysis of combat weapon subsystems. There is a recognized deficiency in the area of compatible ship design modules that allow weapon system concepts to be quickly configured and analyzed. A modeling and analysis to ...

THE PROPOSED PROJECT IS TO DEVELOP A TECHNIQUE WHICH WILL PREDICT THE LOCATION OF ENEMY SURFACE UNITS BASED ON CURRENT TACTICAL DATA, ESTIMATES OF PROBABLE ENEMY TACTICS, AND THE "NEGATIVE INFORMATION" GAINED FROM UNSUCCESSFUL SEARCH FOR THE UNIT. IN ADDITION, WE WILL IMPLEMENT THE TECHNIQUE IN A PROGRAM FOR TEST AND EVALUATION PURPOSES. THE FOUNDATION FOR THIS TECHNIQUE WILL BE THE ALGORITHMS USE ...
