Abstract:Submarines have a need for situational awareness at all times. They are equipped with Fat Line acoustic arrays such as the T-16 and the TB-34 in order to provide this awareness. However, at low tow speeds the array droops from front to back and also loses straightness. This spatial distortion… more

The MDP-TDA will comprise a… more
Abstract:Laser designation and marking is critical in today's high precision combat environment. Performance is limited by how well the soldier can hold the laser beam onto the target. Current fielded laser designator systems minimize beam pointing error by employing a heavy'stabilized'mount… more
Abstract:Dual mode seekers can increase lethality, particularly in GPS denied environments or in situations where precision targeting is required, for example in areas where collateral damage must be minimized. The objective of this proposal is to provide a dual mode sensor that provides the greatest utility… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
