The Award database is continually updated throughout the year. As a result, data for the given year is not complete until April of the following year. Annual Reports data is a snapshot of agency reported information for that year and hence might look different from the live data in the Awards Information charts.

  1. Submarine Sensor Environmental Inference---- 18-075

    SBC: METRON, INCORPORATED            Topic: N182135

    A new optimal sequential Bayesian algorithm is proposed that processes ambient ocean noise collected on the submarines passive sonar sensors into estimates of key aspects of the water sound speed profile (SSP), sea state (SS), and bottom loss (BL). Two modes of operation are proposed. In tracking mode, the software tracks changes in the environmental parameters and sends real-time updates to the s ...

  2. Submarine Sensor Environmental Inference

    SBC: KSA, LLC            Topic: N182135

    The Base and Option propose applying machine learning (ML) deep learning (DL) methods to estimate the Waveguide Invariant (WGI). The ML and DL application also provide prior parameterization of the waveguide. Data fusion methods generate Energy Spectral Density (ESD) and Empirical Orthogonal Functions (EOF) to characterize the uncertainty of the sound speed profile in the water column from which t ...

  3. Underwater Low Noise Acoustic Sensor System

    SBC: Intellisense Systems, Inc.            Topic: N182136

    To address the Navys need for a compact low noise hydrophone sensor for use in sonobuoy array systems, Intellisense Systems, Inc. (ISI) proposes to develop a novel Underwater Low Noise Acoustic Sensor (ULNAS). It will utilize new piezoelectric single crystal materials with enhanced electromechanical coupling characteristics with high sensitivity and custom-developed low noise preamplifier electron ...

  4. A novel Under Water Acoustic Sensor (UWAS)

    SBC: Chromologic LLC            Topic: N182136

    The U.S. Navy is seeking a low-noise, highly sensitive underwater acoustic sensor. Next-generation sonobuoys require more acoustic sensors packaged into the same fixed volume. Reduction in the volume of piezoelectric materials in an acoustic sensor can pose many challenges, such as increase in susceptibility to thermal noise, and can compromise performance. To address this urgent Navy need, Chromo ...

  5. Compact Low Noise Acoustic Sensors for Sonobuoys

    SBC: SEALANDAIRE TECHNOLOGIES, INC.            Topic: N182136

    As foreign submarines become increasingly quieter, there is an ever-present need to improve the performance of passive surveillance systems to increase the probability of detection and ability to resolve critical signature differences useful for classification. Passive acoustic surveillance system such as sonobuoys typically employ arrays of hydrophones, configured to discriminate against backgrou ...

  6. Compact Low Noise Acoustic Sensors for Sonobuoys

    SBC: MSI Transducers Corp.            Topic: N182136

    Through this effort, the team of MSI Transducers and QorTek will develop a compact, low-cost, low-noise acoustic sensor for sonobuoys. The MSI concept fully utilizes its expertise in the design, development, and fabrication of transducers, combined with QorTeks expertise in power electronics, underwater amplifiers and next generation piezoelectric materials, to develop a compact low-noise system.

  7. Computational Analysis of Missile Flight Through Rain

    SBC: THEOFANOUS & CO            Topic: N182110

    Our problem is to determine whether raindrops can survive the shock environment ahead of missile optical components to a degree that they become a damage concern. An initial assessment made for this proposal indicates that the relevant time scales measure in 5-20 microseconds and the Weber numbers (a measure of breakup regime and intensity) reach out to 2 106. We demonstrate that the relevant brea ...

  8. Computational Analysis of Missile Flight Through Rain

    SBC: DYNAFLOW, INC            Topic: N182110

    Development of an efficient device capable of concentrating ultrafine radioactive particulate aerosols is essential to the detection of nuclear detonations using a Radionuclide Aerosol Sampler and Analyzer (RASA) system as well as U.S. Navys development of a fast acting naval radiation detection system. We propose to develop an efficient device for ultrafine particulate aerosol concentration and s ...

  9. Development and Validation of a Computational Tool for Missile Flight Through Rain

    SBC: CFD Research Corporation            Topic: N182110

    The survivability of tactical missiles through adverse weather is difficult to predict, because of the dependency on many variables and the unpredictable nature of weather. This proposal is focused on an effort to develop and test a physics-based methodology for the prediction of the droplet distortion and demise in the flow field around missiles in supersonic flight. Our technical approach of Pha ...

  10. Computational Analysis of Missile Flight Through Rain

    SBC: Integration Innovation, Inc.            Topic: N182110

    The current state of weather requirements definition for tactical missiles is outdated providing operational decision makers little confidence in the performance of missiles in any environment other than blue-sky. The challenge is understanding detailed physics features like drop shape change through a shock, and then being able to apply those at the system level for vehicle performance assessment ...
