In complex man-machine systems, increasing performance of computing and sensor technology often places proportionate new demands on system operators. For example, in Naval sonar systems, tremendous increases in sensor and signal processing capacity haveimposed increasingly difficult demands on sonar operators conducting search. Consequently, overall system effectiveness is reduced and varies wid ...

Daniel H. Wagner Associates, Inc., with Science Applications International Corporation (SAIC) as a subcontractor, will develop an Intelligence, Surveillance and Reconnaissance Tactical Decision Aid (ISRTDA). This system will carry out Level 2 data fusionthat will significantly improve mine warfare situational awareness within the maritime littoral region. As defined by the Joint Directors of Labor ...

The goal of the project is to provide a hardware feasibility demonstration of a compact and lightweight modern power electronics incorporating advances in switching topologies, components and subsystem designs for inductive loads as to minimize the weightand power costs. The proposed system would incorporate high energization electronics to attain fast slew rates and pc/DSP user interface for simp ...

To overcome the problems and performance limitations of traditional electronic compass designs and to achieve better performance at a lower cost, an innovative, simpler, more robust magnetic heading sensor is being developed. The approach is based on thethesis that heading sensor accuracy can be made better (and the heading sensor less complex and expensive) than traditional electronic compass de ...

The Shallow Water Directional Active Measurements (SWDA) hascompleted a successful Phase I SBIR and is ready for Phase II.The proposed plan for Phase II is to develop the active sourcesand receiver prototypes for the active measurement portion ofTactical Acoustic Measurement (TAM) Sonobuoy. Acoustic moduleswill be fabricated and sea tested to gather data to confirm thatthe data collected is compa ...

Active sonar systems face a significant declutteringproblem especially when operating in shallow water. In futuremulti-static, multi-receiver search missions, the number of alertsis expected to increase dramatically. Tactical scenarios presenta further complication because response time is critical and, as aresult, classification in the fewest number of pings is cruciallyimportant. Historically ...

Sonalysts, Inc. proposes applying the concepts developed in Phase I toward the design and development of a prototype Combined Arms Training Support System (CATSS). This prototype will demonstrate the potential for low-cost simulations to be integratedinto training environments. The training audience for the CATSS prototype would range from deployed high-level Naval staff officers to Marine exped ...

A review of acoustic propagation in Shallow-Water (SW) shows thatactive sonar detection ranges are generally limited byreverberation caused by backscatter from the surface, biologicalpopulation, and the bottom. The effects are exacerbated in theVery-Shallow-Water (VSW) and Surf Zone (SF) due to air-bubblesfrom breaking waves and sediment stirred-up by wave action.These unsavory acoustic condition ...
