Physical Sciences Inc. (PSI) proposes to design, develop, and demonstrate a portable, non-invasive, real-time sensor to assess the chemical and physical health of solid rocket motors as a function of age without affecting the motors integrity nor having direct contact with the propellant. In Phase II, a sensor to monitor specific gas species that are markers of the chemical and mechanical aging pr ...

Combining information from disparate sensors can lead to better situational awareness and improved inference performance; unfortunately, traditional multi-sensor fusion cannot capture complex dependencies among different objects in a scene, nor can it exploit context to further boost performance. Integrating context information within a fusion architecture to reason cohesively about scenes of inte ...

Triton, together with our academic and industrial partners, proposes to develop and fabricate dynamic filters based on metamaterials. These dynamic filters are being engineered to enhance the efficacy of focal plane arrays used in interceptor sensors, resulting in significant cost savings. The filter will offer a dynamically tunable pass band, which will reject stray light coming in off-wavelen ...

We aim to build and demonstrate an innovative photonic true time delay solution which alleviates the fundamental problem of cascaded optical switches, and additionally offers several significant benefits. The device uses wideband spatial-spectral (S2) holographic optical memory materials to store and access several broadband time delay gratings. Broadband optical chirps are used to create these ti ...

Missile Defense Agency is seeking new technologies to reduce the tendency to form tin whiskers in electronic assemblies and microelectronic devices. RoHS regulations enacted by the European Union have generated a global shift toward Pb-free electronic components and circuitry. Pb-free solders create reliability problems in military applications such as aircraft and missiles that are subject to h ...

Traditional RADAR implementations suffer from bulky transmitters with cluttered microwave plumbing and antenna support systems that make systems expensive. Today, phased array transceiver architectures providing moderate power (10–100W) can provide RADAR performance with beam-steering capabilities with modest size of the systems. However, these conventional phase array architectures do not scale ...

SET, Inc. proposes to develop lattice-matched AlInN/GaN HFET structure on free-standing GaN substrate. By employing native low-defect GaN substrates and by using lattice-matched heterostructures with the incorporation of indium, we expect dramatic enhancement of these HFET in power density, reliability and high frequency operation. Homoepitaxial growth on native substrate and the use of AlInN/GaN ...

Ballistic Missle Defense (BMD) systems vary wildly in size and scope and include ground-based interceptor platforms with anti-ballistic missile (ABM) warheads, air-based high-power laser platforms such as the Airborne Laser (ABL), and ship-based systems such as the Aegis BMD system. The problems addressed in this proposal are the traditionally large sizes, number of support systems required, and l ...

It is proposed to develop, model, and demonstrate composite case materials with sympathetic responses to slow cookoff. In phase II, the proposed study will focus upon conducting subscale SCO testing on composite case materials and validate a physics based modeling and simulation tool. Subscale motor case dimensions will be analogue to a specific MDA rocket booster.

This Phase I STTR proposes to develop Focal Plane Array (FPA) based on Corrugated-Infrared Hot Electron Transistor (C-IHET) technology as a passive sensor for discrimination seekers. The initial goal of achieving high sensitivity with operating temperature >77K for C-IHET in the 8 - 12 µm LWIR spectral region will be investigated. This IHET effort will be developed in collaboration with the US ...
