Defeating Commercial Drone Threats with Open-Source SDR

  • Magazine Article
  • TBMG-35353
Published 2019-10-01 by Tech Briefs Media Group in United States

It’s nearly impossible to look at technology news without seeing an article about drones. Whether detailing how Amazon wants to use drones to deliver packages or revealing amazing aerial video of drones following Olympic snow-boarders, commercial drones are ubiquitous. Drone emergence has benefited many applications including sports broadcasting and wildlife preservation wilderness surveys. Offering powerful, intelligent software, drones are becoming less expensive and easier to use, with substantial operating range.

SnowMicroPenetrometer Applications for Winter Vehicle Mobility

  • Magazine Article
  • TBMG-35361
Published 2019-10-01 by Tech Briefs Media Group in United States

The U.S. Engineer Research and Development Center (ERDC) Military Engineering Program on Remote Assessment of Infrastructure for Ensured Maneuver (RAFTER) Boreal Aspects of Ensured Maneuver (BAEM) identifies the need for modeling over-snow vehicle performance, as many factors related to vehicle setup and land surface condition contribute to vehicle efficiency. Accurately estimating snow macromechanical characteristics—such as elastic modulus, stiffness, and strength—is critical for understanding how effectively a vehicle will travel over snow-covered terrain.

A 'STEP' Forward for Product Lifecycle Management

  • Magazine Article
  • TBMG-35365
Published 2019-10-01 by Tech Briefs Media Group in United States

The existence of countless proprietary file formats and the exchange of 3D CAD data has been a significant problem since the beginning of 3D CAD modeling. CAD applications and methods using digital data are constantly changing, which predicates the need for a solution to share validated and accurately translated data. Thus the birth of STEP242.

Green’s Function Extraction from Atmospheric Acoustic Propagation

  • Magazine Article
  • TBMG-35363
Published 2019-10-01 by Tech Briefs Media Group in United States

Acoustic waves propagating in the atmosphere may undergo many effects including refraction by temperature and wind velocity gradients, scattering by atmospheric turbulence, absorption by the atmosphere (fluid), diffraction by terrain features, and absorption and reflection by a porous ground. As a result, there may be insonification in acoustic shadow zones, amplitude and phase fluctuations of the propagating sound signals, loss of signal coherence, changes in the interference maxima and minima of the direct ground reflected waves, and multipath effects. Understanding these effects is important for a variety of military applications, such as acoustic source localization and classification, noise propagation in the atmosphere, and the development of new remote sensing techniques of the atmosphere.

Defining an Open System Architecture Standard for Defense Systems

Aerospace & Defense Technology: October 2019

  • Magazine Article
  • 19AERP10_04
Published 2019-10-01 by SAE International in United States

For many years now, there have been efforts within the US defense community to adopt “Open System Architecture” principles (or OSA) for defense computing platforms. Stretching back to the mid-2000's there have been numerous efforts by all service branches to define sets of OSA principles or requirements on the embedded computing systems they procure and deploy. While these efforts have resulted in widespread adoption of POSIX functions for common tasks and a gradual shift in the use of common form factors and technologies such as VPX and Ethernet, there are still wide disparities between products from different suppliers, which creates difficulties for integrators. Product variations also make technology insertions or system configuration changes expensive, time consuming, and often locked to a particular vendor.

Technique Locates Robots and Humans in GPS-Challenged Environments

  • Magazine Article
  • TBMG-35278
Published 2019-10-01 by Tech Briefs Media Group in United States

An algorithm enables localization of humans and robots in areas where GPS is unavailable. The Army needs to be able to localize agents operating in physically complex, unknown, and infrastructure-poor environments. This capability is critical to help find dismounted soldiers and for humans and robotic agents to team together effectively.
