HYPRES, in collaboration with University of Waterloo, proposes to develop a unique mixed-signal integrated circuit (IC) technology for radio frequency (RF) receivers. Using Niobium ICs, we have developed a family of receiver front-ends capable of direct digitization of RF signals up to microwave frequencies (20 GHz). Using Josephson junctions as active devices, this Digital-RF technology features ...

It is proposed to develop and build a prototype system of active magnetic shielding for superconductor electronics packaged on commercial closed-cycle cryocoolers. In this system, the residual magnetic fields inside passive mu-metal shields protecting the heart of the electronics - the superconductor digital integrated circuits and multi-chip modules will be measured by magnetic field sensors base ...

The goal of this project is to develop a digital-RF receiver system to enable direct digital reception from a SIGINT antenna array. In Phase I, we designed a two-input prototype chip integrating two oversampled delta ADCs with a common clock source, and two on-chip digital decimation filters. In Phase II, we propose to design, build, demonstrate, and deliver a complete cryocooled system with a dua ...

We propose to design and build a miniaturized pulsed terahertz (THz) spectrometer weighing less than 3.5 lbs, capable of real-time stand-off detection and identification of explosives and related compounds. The bandwidth of the THz system spans from 0.1 THz to 4 THz, and full waveform acquisition speeds up to 100 Hz. The room-temperature balanced detection system is one of the most sensitive THz w ...

HYPRES in collaboration with Stony Brook University proposes to develop flip-chip bonding technology for assembling up to 4-chip MCMs operating at cryogenic temperatures. This will address the critical area of the MCM technology development and transition to full commercialization of the superconductor MCM technology for DoD and commercial satellite and wireless communications markets. The ultimat ...

A novel coating technology is proposed for increased wear and improved li fe and reliability of commutator bars in electrical sliding devices found in manned and unmanned underwater vehlilles. Diamond-Like Nanocomposite (DLN) coatings represent a famil Of thiWrfilms that bxhibit unique combinations of technologically interesting properties including high adhesion to virtually any substrate (inclu ...

HYPERSONIC AND SUPERSONIC SPEEDS ARE FEASIBLE DUE TO ADVANCES IN AEROSPACE ENGINEERING, VEHICLE DESIGN, AND PROPULSION TECHNOLOGY. THE EFFICIENCIES, RELIABILITY, AND ULTIMATE POTENTIAL OF AIR BREATHING PROPULSION SYSTEMS HINGE UPON NEW MATERIALS THAT CAN SURVIVE THE HARSH COMBUSTION ENVIRONMENTS. HAFNIUM AND ZIRCONIUM CARBIDE AND BORIDE MATRICES ARE CANDIDATE MATERIALS SYSTEMS, BUT ONLY IF MANUFAC ...

MANY INFRARED AND ELECTRO-OPTICAL IMAGING SYSTEMS ARE CONFOUNDED BY FOG AND DUST. MILLIMETER EAVE IMAGING SYSTEMS WOULD NOT BE AFFECTED BY THESE BATTLEFIELD OBSCURANTS. HOWEVER, THE LIQUID HELIUM COOLING REQUIREMENT OF TODAYS HIGH PERFORMANCE LOW NOISE MIXERS IS BLOCKING THE DEPLOYMENT OF ADVANCED MILLIMETER WAVE COMMUNICATIONS AND IMAGING SYSTEMS. IN PRINCIPAL, JOSEPHSON MIXERS FABRICATED WITH TH ...

This SBIR project will determine the feasilibility of acoustic interference rejection techniques for a submarine acoustic intercept system. The signal processing techniques developed will permit the continuous tracking of active weapon sonars in the presence of interference from countermeasures and other sources. Existing submarine acoustic sensors will be used. Multiple emitter location techniq ...

The current generation of high-frequency active 3-D acoustic imaging systems presents a challenge to the covert use of Underwater Vehicles (UVs) by Special Forces teams. An acoustic intercept capability is needed to detect active signals before the UV is detected, so that it can vector away from the source. The team of Advanced Acoustic Concepts and Montana State University propose to design and p ...
