Sonar Systems Deep Learning for Clutter Reduction in Multi-static Coherent Active Sonar Systems Enhanced contact screening for MAC missions will be accomplished by adapting deep learning techniques developed by researchers for image processing to perform pattern recognition on the Bayesian target state estimator for MAC.
The state estimate, a probability mass function encapsulating the existence of a target and its potential position and velocity, containsdata points for every ping.
This information will serve as the input for a deep convolutional neural network which will label regions of the field as target, bottom clutter, ephemeral clutter, or empty.
This labeled map will be used to reduce clutter by improving snippet scores, and increasing the speed with which persistent clutter is identified by MAC.
Other improvements include an enhanced operator display and better ping control algorithms. Reliable Target Area of Uncertainty from an Underwater Acoustic Source SSC is developing technologies which will accurately estimate areas of uncertainty for selected target echoes.
The area of uncertainty will be significantly reduced by incorporating advanced buoy localization methods and by retrospective multiple hypothesis tracking on selected receivers with lower detection thresholds.
The buoy localization techniques will reduce buoy location errors, sound speed uncertainty, and compass bias errors. The multiple hypothesis tracker will reduce target azimuth errors by repeated measurements of the target's angle of arrival.
We seek to reduce the circular error probability radius by a factor of two 2resulting in a four times reduction in AOU. Accurate and reliable AOUs will be computed from the position probability density function of the target, using in-situ estimates of the relevant target localization parameters.
The buoy localization algorithms and retrospective tracker will be used to assess the effects different buoy patterns have on the resulting target AOU.
Reduced Target Area of Uncertainty will improve target tracking and prosecution. Increasing the number of target detections using a wide area search system will improve system classification performance.
SSC will leverage our Multi-Static Sonar Performance Model MSPMwhich is currently being used for P-8A Increment 3 system studies, to model the current acoustic environment and recommend optimum configurations for sonobuoy spacing, operating depth, ping plan strategies, and pulse settings for a multiplicity of op-areas and threats.
Spread Spectrum Techniques for Sonar Ping Technology This project will focus on software and firmware development that further improves the search and detection phase of Air ASW submarine prosecution using pulsed spread spectrum waveforms. These enhancements will allow for at least four simultaneous sources to broadcast simultaneously.
Estimated probability of detection will increase in difficult submarine detection conditions and search times will be reduced in dense field spacing where single-echo detection rates are higher. The goal for this effort is to develop the real-time software for in-flight testing using an at-sea target.
At the end of this effort, we will have demonstrated our technology in the aircraft during a real mission, and demonstrated its usefulness on at-sea data. To achieve this goal, we will complete the real-time software development of the software.
We will procure 32 modified SSQ sonobuoys and update their interfaces. We will conduct test flights and update simulations. These tasks will be utilized to prepare the software for integration into the MAC signal processing software and identify risks to integration under the Increment 3 program.
This jump start will provide the schedule relief needed to fully develop the operator interfaces that will make the LRT an even more powerful tool. During effort, we will focus on the rapid integration of the LRT software and the development of the operator-machine interface OMI in preparation for the Fleet evaluation.
The option effort will focus on improving LRT performance relative to the baseline software based on the findings of the base effort and the operator evaluation. Ultrasound sensors operating in continuous active sonar CAS mode are a natural fit for measuring relative velocity.
The sensor is always on, allowing for the uninterrupted tracking of the Doppler shift over time. SSC's approach uses Acoustic Doppler to sense motion more directly than imaging or range finding approaches.
This sensing modality does not depend on lighting conditions and a significant range of the ultrasonic wavelengths are relatively immune to backscatter from mist and fog, making it a natural choice for day and night maritime conditions.
MARVEL sensor technology is also highly relevant to advanced driver assistance systems and the sensor suites of autonomous vehicles.
Integrating the multimedia assets of a course can raise a host of issues. In my world, this can be as simple as explaining to a client why screens of text with an out-of-sync voice over will not be effective—to more complex issues, such as determining whether an animation will promote greater comprehension than a series of stills. A good design technique for integrating multimedia into a Web site design would be to put in different types of multimedia, such as music, videos/movies and photos into it. There are several benefits for adding multimedia to a Web site. Oracle acquired Sun Microsystems in , and since that time Oracle's hardware and software engineers have worked side-by-side to build fully integrated systems and optimized solutions designed to achieve performance levels that are unmatched in the industry. Early examples include the Oracle Exadata Database Machine X, and the first Oracle Exalogic Elastic Cloud, both introduced in late .
SSC plans to pursue both military and commercial applications in these areas. Mitigation of Biologically Induced Active Sonar Reverberation in Littoral Regions This effort develops and evaluates features exploiting the swim bladder resonance observed in broadband echoes from fish for automatic screening, reducing mid-frequency active sonar clutter.State of the art acoustics and signal processing.

Nov 20, · The great thing about the Internet in is the ability to integrate several different types of media into your site.
Faster internet connections, cheap bandwidth and free third party multimedia hosting services have made it easy for even the smallest of small businesses to work multi-media into their sites. Since it's well known that different people absorb information in different ways.
Integrating Multimedia Into Your Web Site.
There are two primary paradigms for the discovery of digital content. First is the search paradigm, in which the user is actively looking for specific content using search terms and filters (e.g., Google web search, Flickr image search, Yelp restaurant search, etc.).Second is a passive approach, in which the user browses content presented to them (e.g., NYTimes news, Flickr Explore, and.
