Critical Techniques for High-Speed A/Ds In Real-Time Systems Handbook

To help define the meaning of “high-speed A/D” used in this handbook, we will be focusing primarily on A/D converters with sampling rates higher than 100 MHz. We will review sampling techniques, FPGA technology and we will present the latest Pentek high-speed A/D products and applications based on them.

Software-Defined Radio Handbook

SDR (Software-Defined Radio) has revolutionized electronic systems for a variety of applications including communications, data acquisition and signal processing.This handbook shows how DDCs (Digital Downconverters) and DUCs (Digital Upconverters), the fundamental building blocks of SDR, can replace legacy analog receiver and transmitter designs while offering significant benefits in performance, density and cost.

Putting VPX and Open VPX to Work

Before the advent of OpenVPX, designers of embedded systems took advantage of the extreme connectivity offered by VPX (VITA 46), but were faced with a virtually unlimited number of possible implementations. Specific choices for the control and data channel assignments for each slot, the backplane connectivity, and serial fabrics were often made somewhat arbitrarily to suit the particular needs of the current system. Although following the general framework of VITA 46, each system tended to be so unique, that the boards and backplanes designed for one system were seldom usable in other systems, even from the same vendor.

Porous and Stiff Material for Aircraft Lightweighting

Researchers have developed and manufactured a family of architectures that maximizes the stiffness of porous, lightweight materials. 3D printing and other additive production techniques make it possible to manufacture materials with internal structures of previously unimaginable complexity. Achieving this requires that the internal structures be intelligently organized for maximum efficiency.

The stiffness in the material’s interior is achieved through plate-lattices rather than trusses. These structures that are up to three times stiffer than truss-lattices of the same weight and volume.

Foldable Drone Flies Through Narrow Holes

A new drone was developed that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters, such as inspecting a damaged building after an earthquake or during a fire.

The autonomous, morphing drone has onboard perception and control systems, enabling it to maneuver in tight spaces and guarantee a stable flight at all times.

NASA Experiments Fly on Virgin Galactic Spacecraft

Virgin Galactic’s SpaceShipTwo successfully flew to suborbital space last month with four NASA-supported technology payloads onboard. NASA’s Flight Opportunities Program purchased flight services, the accommodation, and ride from Virgin Galactic for the payloads. During the flight, the payloads collected valuable data needed to mature the technologies for use on future missions.

Improving Performance of Hybrid-Electric Aircraft

Although hybrid-electric cars are becoming commonplace, similar technology applied to airplanes comes with significantly different challenges. University of Illinois aerospace engineers are addressing some of them toward the development of a more sustainable alternative to fossil fuels to power airplanes.

Virtual Runway, Real Pilot Practice

When a plane overshoots the final approach, often the pilot’s natural — and dangerous — instinct is to pitch the aircraft up to slow down and land. It’s one of the leading causes of accidents, especially with small airplanes. But what if that same mistake happened at 5,000 feet instead?

AUDS Goes Undetected With New Ammunition

For the third iteration, the AUDS (anti-unmanned aerial vehicle defense system) recently returned to Fort Sill for the Maneuver Fires Integrated Experiment (MFIX). During the last few MFIX events, the AUDS, which works to detect, track, identify and defeat unmanned aerial vehicles (UAV), has evolved from its design as a simple focused-energy weapon to a non-lethal/lethal system by pairing its focused energy to a 30 mm chain gun. At MFIX 2018, the AUDS evolved again, this time developing a passive detection program.

Wind Tunnel, Lasers Provide Hypersonic Proving Ground

It’s about speed, and Sandia National Laboratories, with a hypersonic wind tunnel and advanced laser diagnostic technology, is in a position to help U.S. defense agencies understand the physics associated with aircraft flying five times the speed of sound. With potential adversaries reporting successes in their own programs to develop aircraft that can be flown at Mach 5 or greater speeds, U.S. development of autonomous hypersonic systems is a top defense priority. That has made aerospace engineer Steven Beresh of Sandia’s aerosciences department and his colleagues at the hypersonic wind tunnel popular lately.
