Abstract:There is currently no convenient, effective way to detect, identify, and geolocate (DIG) personal UHF/VHF radio communications devices in field operations. These are commonly used by adversary command, control, and spotter activity. The techniques used by special ops, search and rescue, and… more
Abstract:Detecting, localizing, identifying, tracking, and intercepting multiple and dispersed missiles aimed at multiple and dispersed defended areas, presents a daunting theoretical and practical challenge. The Scientific Systems Company, Inc. team proposes a foundational, information-theoretic and… more
Abstract:Advanced Unmanned Air Vehicles (UAVs) are composed of complex systems and payloads, whose components can be generally classified as flight critical systems, mission critical systems, and auxiliary systems. Flight critical systems are often designed with redundancy, since failure could prove… more
Abstract:Evolving strategies for distributed EW rely critically on data networks, to communicate emitter detections and geolocations between sensors and C2 and tactical assets. Network reliability has been assumed in strategy development. However, standard IP networks may suffer data loss, delay, and… more
Abstract:New and developmental multi-function radar employ active antenna arrays to fulfill multiple radar modes with a single aperture. This is particularly attractive for unmanned aerial vehicles, where form factor and size are highly constrained. For example, the Multi-Platform Radar Technology Insertion… more
Abstract:Scientific Systems Company, Inc. (SSCI), in collaboration with Spatio Systems LLC and Prof. Bennett at Olin College, proposes to design and implement ENLIV-N, an Effective Natural Language Interface for Vehicle Navigation. This multi-modal user interface will translate natural language directions… more
Abstract:SSCI and RDR Tec propose to develop and implement an on-board Fast On-line pREdiCtion of Aircraft State Trajectories using Integrated Information (FORECAST II) system, as a part of a future comprehensive Integrated Collision Avoidance System (ICAS). The main feature of the FORECAST II system is that… more
Abstract:Scientific Systems proposes to develop a spatio-temporal data analysis toolbox to seamlessly integrate into GIS software so that users can invoke the toolbox for advanced statistical analyses without explicitly leaving their GIS software. The toolbox will have the capabilities for users to… more
Abstract:Detecting, localizing, and intercepting one or more missiles during ascent phase presents a daunting theoretical and practical challenge. Scientific Systems Company, Inc. of Woburn, MA, and its subcontractor, Lockheed Martin, propose a foundational, control-theoretic approach to such problems. It is… more
Abstract:ADS-B reports can be maliciously spoofed to deny airspace to other aircraft including those on DoD missions. Under the Phase I effort, we developed a novel approach that exploits the physical characteristics of the ADS-B transmission signal to determine its validity. We leveraged our proven… more
Abstract:The intelligence community uses the National Imagery Interpretability Rating Scale (NIIRS) to quantify the information that an image analyst can extract from a visible image. NIIRS ratings relate the visual quality of an image to the interpretation tasks for which it may be used. A General Image… more
Abstract:ABSTRACT: The goal of this project is to develop, demonstrate, and implement at EAFB the EVASE:"Extensible Video Analysis of Symbology Events"Matlab toolkit. This system is based on the premise that it will learn symbology events during training by an expert operator, and then… more
Abstract:The objective of this project is to develop a tactical wireless network strategy that offloads TCP/IP traffic to temporary storage or alternate pathways instead of dropping packets from overflowing queues. In Phase I, we adapted DTN strategies for diverting marked packets into external queues when… more
Abstract:U.S. Navy ships require the use of Hazardous Materials (HM) for daily shipboard operations. In order for Ship"s Force to work more efficiently NAVSEA approved the use of satellite storage lockers which are placed in the ship"s work centers, to store a seven day supply of daily use HM.… more
Abstract:Electronic Support (ES) systems are among the fundamental instruments used for threat detection onboard Navy surface, sub-surface, and air platforms. They are tasked to sense the RF environment, to sort out all emitters, measure key associated parameters, and contribute to a comprehensive… more

The core technology is a miniature… more
Abstract:The major components of manmade aerosols are created by the burning of coal and oil. Aerosols are recognized to significantly impact the climate through their effects on solar and terrestrial radiation. Accurate speciation and measurement of aerosol composition is an important first step in… more
Abstract:DESCRIPTION (provided by applicant): Several US agencies and regulators require low-cost chemical sensors for detecting and monitoring environmental clean-up, remediation, and decommissioning processes where groundwater may be contaminated.

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.
