In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

Training in the symptoms of Spatial Disorientation (SD) has shown to be valuable in aiding pilots to recognize its onset and provide a means for mitigating its effects, but such demonstrations have traditionally been associated with specialized equipment and devices. Since the vast majority of pilots for the commercial aviation jet fleet are trained (or recertified) on 6-degree-of-freedom (DOF) h ...

A new paramagnetic crystal, TbPO4, is proposed as an efficient substitute for materials used currently as Faraday rotators in optical isolators in visible and near-IR lasers. It's figure-of-merit is an order of magnitude higher than that of TGG. Aneffective solvent for growing TbPO4 by the high temperature solution (HTS) method is proposed. This solvent is environmentally benign and can universal ...

The proposed antijam concept for interceptor missiles uses an innovative, low-cost, antenna electronics and GPS antenna configuration to receive GPS, and suppress jamming on high-speed, maneuvering missiles. The effort defines an antenna system, commutatorswitch and antijam electronics solution using digital signal processing. The concept detects jamming and optimizes jam suppression at all attitu ...

A CONCEPT FOR THE DETECTION OF CORROSION IN AGING AIRCRAFT USING ACOUSTIC EMISSION MONITORING IS PROPOSED. CORROSION WILL BE LOCATED THROUGH THE EFFECT THAT IT HAS ON AIRFRAME STRENGTH (10% THINNING RESULTS IN 50% FATIGUE LIFE REDUCTION). ACOUSTIC EMISSION TECHNOLOGY USED ON THE F-111 FIGHTER/BOMBER WILL BE ADAPTED FOR USE ON COMMERCIAL AIRCRAFT. PRELIMINARY CONCEPT TESTING ON A BOEING 720B HAS RE ...

Non-cryogenically cooled pyroelectric IR detectors and imaging arrays, using bullk materials, are employed in a great many military and commercial systems. the technological opportunity now exists to increase responsivity and sensitivity (- 10 fold) whilelowering the production costs of such systems by converting to suspended thin film structures. In the Phase I effort and through related progra ...

Structured Materials Industries (SMI) proposes the development of antimonide-based, high-speed, low-power, heterojunction bipolar transistors (HBTs). These HBTs will have advantages over other compound semiconductor HBTs including lower power consumptionand zero turn on voltage. They are also required for the fabrication of all antimonide-based circuits integrating recent advances on optoelectro ...
