DoD cyber infrastructure moving steadily toward full operational capability
What constitutes an act of war in cyberspace? Russia, North Korea, China, and Iran – all made headlines in the past year by conducting malicious acts against the United States. So far, however, their actions do not fall under the category that would constitute an act of war. To counter these nonetheless dangerous threats, the [...]

Modernizing a serial processing code to obtain optimal performance on an OpenVPX digital signal processing module
Serial algorithms can be evolved to a scalable, multithreaded, multiprocess implementation using ubiquitous and well-established high-performance computing (HPC) programming frameworks such as OpenMP and MPI. Such techniques are used in compute-intensive defense, aerospace, and industrial applications.

DoD budget increases impact on defense electronics suppliers
Every month the McHale Report will host an online roundtable with experts from the defense electronics industry – from major prime contractors to defense component suppliers. Each roundtable will explore topics important to the military embedded electronics market. This month we cover the Trump Administration’s Department of Defense (DoD) Fiscal Year (FY) 2019 budget request. [...]

The path to smarter, autonomous radar and EW platforms
Data flowing from radar and electronic warfare (EW) systems to the analyst's screen will determine the course of action in any given mission. Bearing in mind that decisions need to be made, at times in seconds, it's critical for radar and EW systems to quickly sift through that data and turn it into actionable intelligence. To achieve this goal, the defense industry is using artificial intelligence (AI), machine learning (ML), and deep learning (DL) techniques to program these systems and make them into smarter, more autonomous tools.

Using thermofluid simulation to optimize liquid cooling of avionics power systems
Liquid cooling for military signal processing offers advantages in high-power-density systems to dissipate heat at a higher rate than air-cooled systems and to transfer heat further away efficiently for thermal signature control. When using liquid-cooling systems, the challenge is to meet size, weight, and power (SWaP) goals while ensuring design for performance and reliability. A method is presented on how to model, characterize, and optimize the performance of cold-plate designs using 3-D computer-aided design (CAD)-embedded computational fluid dynamics (CFD) simulations to then immediately use this data in a system-level, fluid-dynamics simulation model of a full-pumped, liquid-cooling system. This 1-D/3-D CFD, model-based design approach enables earlier and more accurate evaluation of physical components.

Data-to-decision: Fueling netcentric defense solutions with the IIoT and fog computing
In today's defense arena, traditional tactics using large, fixed systems no longer suffice. A deployed naval strike group might find itself needing to quickly integrate its data systems with those of on-site allies - some of which may be many years older - and process data with these combined platforms in real time. We are now in the era of the industrial internet of things (IIoT), and those who make the most flexible, intelligent use of the data streaming in from a dizzying array of clients have the advantage.

Using RISC-V in FPGAs for strategic defense systems
The defense market is often characterized as slow-moving and a laggard when it comes to high-tech components. The strict certifications and testing that are often required for upgrading military systems generally cannot be rushed. At the same time, though, there is growing demand to speed development cycles for the next generation of strategic defense products.

Radar on the high seas
Modern maritime radar systems for missile defense and navigation have become more precise by leveraging commercial signal processing and radio frequency (RF) components in modular designs that enable commonality with clear technology refresh paths.

VME lives!
As we start a new year, it is customary to look ahead at emerging technologies, both evolutionary and revolutionary. But as the calendar changes, it is also a time to reflect on the past and where we are today. Although recent years have produced few entirely new platforms designed from the ground up, our industry continues to deliver higher levels of performance and new capabilities within existing systems.
