Towed arrays provide the potential for creating synthetic elements located a fraction of the distance between the actual elements, thus sampling the spatial field at a higher rate and allowing for operation at higher frequencies without grating lobes. Synthetic elements may also be used to fill in for failed sensors. The ability of a passive synthetic aperture sonar (PSAS) towed array system to ac ...

The Phase I effort of the SBIR program culminated in the development of algorithms, toolsets and interfaces to detect human activity from video and improve the operator"s wide area situational awareness of live feeds from multiple video sensors in the battlefield. In Phase II, we plan to extend this technology and achieve the following objectives: 1) utilization of scene context extraction algorit ...

This project aims at developing a non focal plane laser protection system consisted of single crystal plates with hidden phase gratings, which can be revealed with exposure to strong laser pulse, and a novel optical shutter based device that follows. The protection system is large in aperture, broad in transparent window (400 nm to 2000 nm) and in field of view, and wavelength-insensitive. The pro ...

Sensor protection against agile-frequency lasers is a critical Army Technology Objective (ATO). We propose simple defocusing of existing sensor optics as a layer within the optical limiting (OL) stack. This requires no additional optical components, and promotes compatibility with other OL stack elements. The challenge resides in computing the inverse filtering operation to recover the in-focus im ...

In this effort, Physical Sciences Inc. will develop and implement algorithms and hardware to perform the fusion of information obtained from multiple LWIR passive hyperspectral sensors to provide the capability to determine the extent, absolute geo-location, and 3-D concentration distribution of chemical threat clouds from mobile platforms. The effort will be conducted in conjunction with Professo ...

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 connectivity is lost or congestion occurs, integrated DTN methods with new OSPF methods, and develope ...

Harmonia proposes to continue development from Phase I of a Large Data Handling Architecture (LDHA). Given sufficient amounts of commodity hardware, its goal is to scale up to ingest a terabyte or more of data per hour from each open source or sensor; store tens of thousands and more of terabyte files; and support operations on databases that use complex structures as table cells, sparse tables, a ...

The amount of new malware encountered daily is accelerating at an unprecedented rate, an explosion that is also reflected in target and attack vector diversity. There has also been a dramatic increase in the use of malware kits, a problem in its own right because kits allow adversaries to easily create one-time-use malware variants for which generic signatures and general solutions are neither pra ...

We propose to develop an easy-to-use, safe, automated, field-portable high-throughput system, with related methods and consumables, to allow for the simultaneous inactivation and extraction of target molecules from pathogenic organisms, such as viruses, and rickettsia and non-rickettsial bacteria, that propagate and/or disseminate in arthropod hosts (herein referred to as Agents). The proposed Sys ...

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 autonomously detect this symbology in long video sequences, resulting in a list of key events to assist the operator in f ...
