Dynetics proposes the use of On-The-Aperture Patch Tuning (OTAPT) as a potential solution for broadband performance from a low profile antenna. This solution is based on the innovative concept of integration of digital switching of tuning elements directly on the aperture surface. A single patch antenna can then be digitally tuned to successively lower frequencies, modifying the patch dimensions ...

Ktech proposes to develop a HV2A methodology for the assessment of nuclear weapon effects on new materials that are candidates for inclusion in strategic and tactical military systems. The methodology (1) provides an estimate of the system requirements and operation environments for each application specific material/structure, (2) establishes the critical response modes, (3) provides a framework ...

Low-temperature MBE grown GaAs (LT-GaAs) contains a high concentration of excess As which gives rise to ultra-fast carrier-trapping time and excellent radiation hardness. In as-grown layers most of this excess As is in the form of As(Ga) antisite defects, of which only ~1% are ionized. Thermal annealing upon overgrowth with a device structure or during device processing results in a decrease of ...

Specific Emitter Identification (SEID) systems have been implemented using narrow hand receivers with fine grained Pulse Repetition Interval (PRI) analysis. The analysis produces a PRI signature on an emitter such that the same emitter is uniquely distinguished from another of the same type, allowing a user to associate an emitter to a specific platform. Using a narrow band tuner for this analys ...

Design of an ultra low power satellite transceiver is needed, which is technically innovative in three areas. First, interoperability with non-geostationary satellite systems as well as conventional geostationary systems is proposed, allowing global coverage, very small antenna, large field of view, and near 100% availability even for poorly sited terminals. Second, digital signal processing tec ...

We propose to develop an improved Explosively-Formed Penetrator (EFP) warhead that in its basic application projects a slug that pentrates the mine's case and detonates the iner explosive. In an advanced, alternate mode, the warhead will project a penetrator capable of neutralization through deflagration. The alternative mode employs reative intermetallic materials in the warhead's main component, ...

The contractor has patented technology for a unique process that directly converts a two-dimensional acoustic disturbance, such as a wave front, into an intensity-mapped visible image in real-time without electronic circuitry; that is, it is a direct pressure gradient imager. The imager relies on the piezo-dichroic properties of a continuous layer of a dichroic material thin film that serves as bo ...

Naval Special Warfare is developing and testing equipment and tactics for neutralization of anti-invasion mines in the very shallow water maritime environment. The device proposed herein, an electromagnetic pulse mine countermeasure device, will enhance the capability of Naval Special Warfare to neutralize mines. The proposed device is expected to be effective against most, if not all, mine types, ...
