A System-Level Modeling Framework for electromagnetic modeling is proposed. The heart of the Framework is a rule-based, whole-object conversion process that takes Computer Aided Design (CAD) geometry and material data and transforms it into valid,electromagnetic geometry and material modeling elements. The CAD Converter creates an

This work will design, develop, and implement a system-level electromagnetic simulation framework that increases the productivity of all participants in an EM analysis of a complex system by providing a collaborative engineering environment in which theparticipants easily construct simulation models, share and re-use data, create computational capabilities that utilize a suite of EM modeling tools ...

The objective is the development of a high power microwave antenna to operate with 100 megawatts pulsed input at L band. Unfortunately, the present dish antennas capable of achieving this objective are too large for use on Army land vehicles (HMM) and airplatforms (Blackhawk). With recent antennas in dielectric materials, forrelectric materials, semiconductors, and plasmas, coupled with advances ...

Astron proposes to develop and demonstrate a series of compact, extremely high power transmit/receive anennas to cover (with a minimum number of antenna elements) the HF through UHF frequency range. These antennas are intended for on-the-move operationsin airborne and also vehicular applications. Antenna miniaturization and broadbanding are stressed.

Develop and test antennas suitable for an unmanned aerial vehicle (UAV) with signals intelligence and communications payloads and the potential to be used with other systems. New ideas are stressed to achieve antenna miniaturization and widebandwidths.The development of a miniaturized broadband antenna covering VHF/UHF frequencies for potential DF systems holds the potential for applications in w ...

Design of next-generation vehicles for the Army must include an analysis of their detectability over a wide range of electromagnetic (EM) frequencies. Of particular interest is the frequency range of 50 to 200 GHz. At these small wavelengths, ground andair vehicles comprise millions of square wavelengths of surface area. The surrounding foliage, as well as earth surface terrains complicates the ...

Defense Planning Guidance (DPG), FY2000-2005 requires the United States (U.S.) Military to develop the capability to rapidly project a dominant ground force anywhere in the world within days. The Army Vision and draft Army Strategic Environments (Draft FM525-5) reinforce the DPG by requiring the right mix of mission tailored, combat-ready land forces and capabilities, including support and sustain ...

This SBIR is concerned with the operational use of acoustic sensors mounted on an operating vehicle to detect and localize targets, including other vehicles, in the surrounding environment. In general, several classes of noise limit the performance ofthese types of acoustic systems. Two key classes are the near field noise generated by the platform itself and the far field noise generated by inter ...

The Army wishes to mount acoustic sensors on operational vehicles and use them to detect and localize other operational vehicles in the vicinity. The effectiveness of such a system can be limited by the noise created by the platform on which the sensorsare mounted. DSR proposes a system that combines noise cancellation techniques with adaptive beamforming techniques in order to simultaneously reje ...

Blast parameter measurement is imperative to improve and verify current theoretical predictions of new weapon effectiveness and structural responses to blasts. A number of variables such as fuse initiation, explosive charge shape, charge burn rate, andambient conditions determine blast wave characteristics and complicate theoretical predictions. Experimental verification of theoretical models is d ...
