Applied Radar, Inc. is developing the Single Channel Open Source Architecture (SCORE) digital receiver/exciter (DREX) card which represents a revolutionary step leap in SWAP-C reduction. The SCORE card is a 3U OpenVPX card which incorporates a single channel of waveform generation, RF Upconversion, RF Downconversion, and waveform capture and processing. Importantly, the design is scalable, and des ...

Since the advent of impulse launching various payloads from Navy and other military combatants, the source of the impulse energy has been either an explosive gas generator (propellant) or stored high pressure gas in a flask. Both of these methods have high maintenance and/or clean-up costs and are typically limited to one type or size of payload per launcher device. This limits operational flexibi ...

The objective of this proposal is to design and develop UHF Satellite communications (SATCOM) circular polarized antennas using advanced metamaterials to achieve high gain performance with smaller dimensions (i.e., size and weight). The metamaterials we propose belong to a class of magneto-dielectric materials. The advantages and disadvantages of dielectric loading applied to electromagnetic devi ...

Yardney Technical Products, Inc., with SBIR partners, Brown University and Fraunhofer LLC, propose to develop a high energy density, high power, bipolar battery. Bipolar battery designs are inherently the most volumetrically efficient batteries. Further, the elimination of the external intercell connections greatly improves the rate capability and solves the issue of making a very low capacity, hi ...

The goal of this effort is to build a fully on-board vision based navigation system for small micro air vehicles (SMAVs) that will allow autonomous flight and navigation in a ship-borne environment. The target platform is a hovering air vehicle of 7cm to 20cm in size with a payload capacity between 2 and 10 grams. Short range navigation, e.g. stability, relative orientation, and obstacle avoidance ...

ABSTRACT: Multi-sensor fusion is a key capability required for effective inferences for timely and accurate strategy and tactical planning. A multi-sensor fusion technology needs to appropriately weigh different image streams according to the uncertainties and errors across different inputs and parameters such as GPS and INS measurements, sensor model parameters, inherent ambiguities of the data ...

Current monostatic radar systems suffer fine tracking and discrimination performance degradation when encountering mainlobe jammers deployed within a reentry complex. As a result our forces may be vulnerable to attack. During Phase I, we have developed distributed aperture techniques for mitigating mainlobe jammers which are ready for evaluation in an operational system context. To accomplish this ...

ABSTRACT: A key requirement for a practical/scalable airborne passive radar system using opportunistic ground emitters such as broadcast TV is the ability to effectively isolate the high-powered direct-path signals from much weaker target reflected ones. Previous passive radars rely on array antennas complemented by multistatic techniques and dedicate/agile decoders for every-possible-type of opp ...

The goal of this project is to take silver-zinc battery technology to a new level for programs important to the Navy. Silver-Zinc batteries provide high energy and power density cells, and since the electrolyte is a water-based alkaline fluid, provide a comparatively safe battery. A disadvantage to this technology is large format cells, which are required to provide high power, do not provide comp ...

Yardney Technical Products in conjunction with Johns Hopkins University Applied Physics Laboratory is proposing to progress development of an advanced monitoring system for batteries, provide a modular battery unit, and develop a system approach to monitor and control multiple power sources and loads. Battery monitoring will be advanced via a technique to determine the internal temperature of each ...
