The U.S. Army Research, Development and Engineering Command (AMRDEC) and Redstone Test Center (RTC) at Redstone Arsenal, Alabama have developed a Ka band, range instrumentation synthetic aperture radar (RISAR) for the purpose of millimeter wave (MMW) target and scene characterization. RISAR was developed as one element of the Advanced Multi-Spectral Sensor and Subsystem Test Capabilities (AMSSTC) program funded and managed by the U.S. Army Program Executive Office for Simulation, Training and Instrumentation (PEO STRI), Project Manager for Instrumentation, Targets and Threat Simulators (PM ITTS). The key objective of RISAR is the collection of MMW SAR data that can be used to develop high resolution target and terrain models for use in digital and real-time hardwarein- the-loop simulations. The purpose of this presentation is to provide an overview of RISAR development and implementation. Example results of funded data collections will be presented with an emphasis on the system's 3D target modeling capabilities for ground targets, and wake characterization capabilities for littoral targets. © 2010 Copyright SPIE - The International Society for Optical Engineering.

State-of-the-art hardware-in-the-loop (HWIL) test facilities have been established and in operation at the U.S. Army's Aviation and Missile Research, Development, and Engineering Center (AMRDEC) in McMorrow Laboratories, on Redstone Arsenal Alabama for over 37 years. These facilities have been successfully developed and employed supporting numerous tactical and interceptor missile systems. The AMRDEC HWIL facilities are constantly in a state state of modification and revision supporting evolving test requirements related to increasingly complex sensor suites, guidance implementations, and employment strategies prevalent within both existing and emerging aviation and missile programs. This paper surveys the role of the U.S. Army Aviation and Missile Research, Development, and Engineering Center (AMRDEC) in the development and operation of HWIL test facilities and the implementation of new, innovative technologies that have been integrated within facility test assets. This technology spans both the Near IR (NIR- 1.064um) and IR (3 - 12um) and RF (2 - 95 GHz) operating ranges. The AMRDEC HWIL facilities represent the highest degree of simulation fidelity, integrating all the major parts of a HWIL simulation including tactical missile and seeker hardware, executive control software, scene generation, and NIR, IR or RF scene projection systems. Successful incorporation of scene generation and projection technologies have become a key thrust of the AMRDEC HWIL development focus, with the intention to adapt and anticipate emerging test element requirements necessitated by future system sensing technologies. © 2012 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

This article describes a mathematically based human circulatory model. The model consists of lumped elements made of venous, arterial, peripheral, pulmonary vein and artery segments. A heart model is simulated using 4 chambers (left and right atriums and ventricles). The heart pump mechanism is operated by a simple piston based models for each of the chambers. The simulation consists of 19 (states) first order differential equations. and simulated with Matlab and Simulink. The simulation computes volume, flow rate and pressures in each segment. © 2012 The authors and IOS Press. All rights reserved. Source

We will use our thorough understanding of AMRDEC radar scene generation and SAR processing to study various techniques for generating spatially correlated scenes. The technique(s) that produces the desired SAR scene at the desired update rate will be chosen. This technique(s) will be further developed and specified for use in the AMRDEC common scene generator. It will be marketed to developers of multispectral seekers for use in efficient SAR generation in simulations.

With the ubiquity of mobile devices and the large disparity in screen sizes it is imperative for applications to be able to adapt to a wide variety of devices and platforms easily and transparently. As such, it is required that to do so there must be an intelligent framework that is powerful enough to coordinate and adapt to these ever changing screen size requirements easily and seamlessly. This proposal outlines the development, testing, marketing and profound impacts of a framework that could handle user-interface adaptation completely transparently to the user.
