Long-duration wide-area surveillance missions increasingly are space-based. MEO orbits offer space-based radar systems more time on station, but require very large array apertures on the order of 100m in diameter. Achieving larger apertures with smaller,lighter launch packages and stable on-orbit pointing is a challenge that E-Textiles promises to meet. Textile processes can be used to achieve a l ...

"Current man portable antennas are heavy, rigid, telescoping or umbrella like contraptions, which limit the mobility and speed of a deployed unit. We propose to improve the weight, storage size, and ease of deployment of a portable antenna through the useof electronic textiles as described in this proposal. Planar antennas have been manufactured on thin films and rolled into position, however a ri ...

"A multi-channel transmit array is to be developed for high-speed digital communications and radar applications. Digital beamforming (DBF) will be combined with direct digital synthesis (DDS) waveform generation to achieve a system capable of using bothwaveform diversity and spatial diversity. Multiple simultaneous transmit beams will be generated that may be configured and scanned digitally. Usin ...

Digital Beamforming (DBF) technology offers several advantages to phased-array radar and communication systems over previous analog phase shifters including performance, versatility and cost. Previous array phase-shifter technology can be classified aseither fixed delay, employing switched delay lines, or variable delay, using ferrite phase shifters. The fixed-delay systems suffer from lack of ver ...

An X-band interferometric radar (XBIR) system employing digital beamforming (DBF) is proposed to supplement the S-band multi-mission radar (MMR) phased array currently under development by Syracuse Research. This auxiliary X-band array will bolt onto theapproximate 1.5 x 2.0 meter MMR array and provide a precision tracking capability for fire control. The two radars will operate cooperatively in v ...

Phased-array radar employing wideband digital beamforming (DBF) offers the potential for detecting and tracking incoming cruise missiles while defeating electronic countermeasures such as chaff, jamming and anti-reflective coatings. A wide instantaneousradar bandwidth is essential for defeating these threats, resulting in improved range resolution and target signature. Digital beamforming may be u ...

THE RESEARCH HEREIN PROPOSED IS INTENDED TO ADDRESS THE CONTINUING PROBLEM OF ESTIMATING SOFTWARE COSTS OVER THE LIFE OF LARGE AND COMPLEX SOFTWARE PROJETS. THE RESEARCH WILL ADDRESS ALL FACTORS THAT AFFECT SOFTWARE COSTS FROM A FUNCTIONAL STANDPOINT AS OPPOSED TO THE TRADITIONAL LINES-OF-CODE (PROGRAM SIZE) APPROACH. THE FACTORS WILL BE TRANSLATED INTO A MODEL THAT EMPHASIZES THE IMPORTANCE OF IN ...

THE NEED FOR SOPHISTICATED DATABASE MANAGEMENT SUPPORT IN NAVY COMMAND AND CONTROL SYSTEMS CONTINUES TO GROW. HOWEVER, CONVENTIONAL DATABASE MANAGEMENT STRATEGIES AND TECHNIQUES ARE NOT CURRENTLY MEETING THE UNIQUE NEEDS OF NAVY DECISION SUPPORT SYSTEMS, WHICH REQUIRE EXTENDED CAPABILITIES FOR HANDLING UNCONVENTIONAL DATA FORMATS AND TEMPORAL INFORMATION. IN THIS PROPOSAL, AQUIDNECK MANAGEMENT ASS ...

THIS PROJECT OUTLINES A RELIABILITY AND MAINTAINABILITY KNOWLEDGE BASE AND THE HYPERTEXT INTERFACE REQUIRED TO TRANSPORT THIS DATA INTO COMPUTER-AIDED DESIGN (CAD) ENVIRONMENTS. THE PRIMARY FOCUS OF THE PROPOSAL IS THE DEVELOPMENT OF THE FOUNDATION FOR AN ENGINEERING RELIABILITY AND MAINTAINABILITY INFORMATION PRESENTATION SYSTEM TO SUPPORT ELECTRONIC CIRCUIT AND SYSTEMS DESIGN ENGINEERS IN A CAD ...
