Abstract:Arete Associates proposes improving VLF channel capacity, bit error rate, and range of operations for submarines and supporting aircraft. By implementing adaptive cancellation of atmospheric noise, the SNR of the received signal will be enhanced as much as 6dB at the VLF receiver. The noise… more
Abstract:The U.S. Navy would benefit greatly from a tool that could produce realistic scenes of the littoral environment based upon standard meteorological and oceanographic inputs in near real time; simulate a wide range of sensors aboard platforms above, below, or on the ocean surface; and allow the user… more
Abstract:Rapid and reliable identification or discrimination of friendly and hostile targets at beyond visual ranges remains a major technical challenge that may be best served by advances in ladar technology. Next-generation intelligence, surveillance and reconnaissance (ISR) ladar systems will tackle the… more
Abstract:Arete will define the algorithmic, sensor, and platform requirements needed to perform airborne radar-based detection, tracking, and characterization of marine mammals in ocean or littoral battle spaces during Naval anti-submarine warfare (ASW) training and testing activities. Achieving performance… more
Abstract:Processor manufacturers are no longer able to rely on near Moore's Law like increases in straight line instruction throughput and clock frequency to provide users with the performance increases that they have become accustomed to. Instead, hardware developers have begun to take a different approach… more
Abstract:Current airborne search techniques rely on an operator to look out a window with binoculars or at a video monitor connected to a turreted camera system. Disparities in crew training, experience, qualification, and attentiveness (as well as fatigue) lead to an undesirable variability in manual EO/IR… more
Abstract:To counter emerging threats of theater ballistic missiles the Missile Defense Agency (MDA) has sponsored the development of the Airborne Laser Weapons System (ABLWS). For the ABLWS to defeat multiple targets over the theater of operation it must be capable of accurately tracking multiple targets… more
Abstract:Passive polarimetry will be used in an innovative fashion to extract the ocean surface slopes. The Phase II program will consist of the construction of a state-of-the art imaging polarimetry sensor system, the further development and refinement of the algorithms for extracting the slope values from… more
Abstract:Passive electro-optical (EO) imaging of submerged submarines has been the subject of research for almost three decades. Previous efforts, which have focused on the use of passive, multi-spectral imaging (MSI) methods to detect, classify, and localize submerged submarines, have been hampered by… 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.
