  1. ACCURATE PASSIVE RANGING TECHIQUES

    SBC: ASTRON WIRELESS TECHNOLIGIES, INC.            Topic: N/A

    Monopole and dipole antennas have been determined to radiate most efficiently when the size of the antenna is proportional to the frequency being transitted or received, ie.e, one-quarter, one-half or one wavelength. As the operating frequency is varied from that ideal frequency, nulls begin to develolp which threaten the integrity of the communication link. Experience has shown that small excusio ...

  2. ACOUSTIC DIRECTION AND RANGE TRANSDUCER FOR DIVERS

    SBC: EMPIRICAL TECHNOLOGIES CORPORATION            Topic: N/A

    The contractor has patented technology for a unique process that directly converts a two-dimensional acoustic disturbance, such as a wave front, into an intensity-mapped visible image in real-time without electronic circuitry; i.e., it is a direct pressure gradient imager. This device can allow a small, battery powered acoustic source to be easily located and ranged using a small flashlight sized ...

  3. ACOUSTIC PROPAGATION PATH DETERMINATION

    SBC: PLANNING SYSTEMS, INC.            Topic: N/A

    THIS PROPOSAL PRESENTS AN INNOVATIVE APPROACH TO DETERMINING THE PROPAGATION PATH OF ACOUSTIC DATA RECEIVED BY A THIN LINE TOWED ARRAY. WE MAKE USE OF THE LATEST DEVELOPMENTS IN SEAFLOOR ACOUSTIC MODELING CAPABILITY AS WELL AS EMPLOYING THE EMERGING AND POWERFUL TECHNIQUES ASSOCIATED WITH ARTIFICAL NEURAL NETWORKS. THE PROPOSED NEURAL NETWORKS WILL BE DESIGNED TO IDENTIFY THE PATH OF PROPAGATION F ...

  4. Acoustic Towed Array Position Measurement System for Nuclear Submarines

    SBC: DDL Omni Engineering, LLC            Topic: N/A

    DDL OMNI Engineering proposes to design a secure system for the continuous, real time acoustic measurement of towed array position relative to the host submarine. By using focused transmit and receive assemblies, pseudo- random spread broadband signals, and relatively high carrier frequency, the transmission level will be minimized so as to be virtually undetectable by a non-dedicated system ...

  5. Acousto-Ultrasonic Method for the Detection of Adhesive Bond Integrity

    SBC: Materials Modifications Inc.            Topic: N/A

    Composite materials find increasing importance as structural materials for modern lightweight and low cost aircraft. Structures using composite materials essentially rely on the integrity of adhesive bonds for their structural stability. A major limitation in employing composites in critical structures is that the existing methods of testing the integrity of structures are not adequate to a ...

  6. ACTIVE NOISE CONTROL

    SBC: SVS R&D SYSTEMS, INC.            Topic: N/A

    THE PROBLEMS OF ATTENUATING DUCTED NOISE AND DISTRIBUTED NOISE ARE ADDRESSED USING ACTIVE NOISE CANCELLATION TECHNIQUES. FOR DUCTED NOISE, A COMBINATION OF COMMERCIAL ANC EQUIPMENT WITH LOW PRESSURE DROP MUFFLERS IN AN SVS PROPRIETARY CONFIGURATION WILL BE EXAMINED. COST AND PERFORMANCE TRADES BETWEEN THE ACTIVE CONFIGURATION AND PASSIVE MUFFLERS WILL BE MADE AND AN EXPERIMENT WILL BE DESIGNED FOR ...

  7. ACTIVE SURVEILLANCE SYSTEM SIGNAL PROCESSING FOR DENSE MULTIPATH NEAR LAND WARFARE

    SBC: DIGITAL SYSTEM RESOURCES, INC.            Topic: N/A

    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 ...

  9. Adaptive Beamforming for Littoral Waters

    SBC: DIGITAL SYSTEM RESOURCES, INC.            Topic: N/A

    This project proposes preliminary investigations to prove the feasibility of four techniques for improving Adaptive Beamforming performance in littoral environments. Emphasis is placed on tradeoffs between algorithm efficiency and performance. The littoral acoustic environment is characterized by near and far field targets and dense dynamic near and far field directional interference at man ...

  10. Adaptive Beamforming for Multistatic Active Sonar

    SBC: AMRON CORPORATION            Topic: N/A

    Amron and its subcontractor BBN propose to show the feasibility of a broadband time-domain adaptive beamformer (ABF) to suppress uncorrelated narrowband sources and multipaths from correlated impulsive sources. The work is motivated by political developments which have emphasized warfare in littoral areas, where a key problem facing active sonar is scattering from topographic features. Activ ...
