Higher-density RF is on your radar with VITA 67.3 standard - Blog

March 29, 2018

These days, multifunction radars handle functions from surveillance to jamming to fire control, and can track multiple targets in both short- and long-range threats. That means one thing for your active electronically scanned array (AESA) radar design--you need a lot more signal processing power.

VPX power supplies and EMI filters - Blog

Leo Carbonneau Milpower Source

Electro-magnetic interference (EMI) filters are critical components in any electrical design, especially in support of military systems requiring partial or complete qualification to MIL-STD-461. EMI filters are designed to reduce high frequency conducted and radiated electronic noise which may create interference with other electrical devices. Embedding EMI filters into the power supply, a potential signal source, is a key feature in any power supply design.

MIL-STD-1553: Do we know too much - or too little? - Blog

February 28, 2018

Abaco Systems

MIL-STD-1553 is a very tried and true, well known, serial interface for the space and aviation industry that was originally developed for critical avionics interfaces that were required to solve the problem of connecting the many sensors and controls around an aircraft and relaying information between them and the crew. Key requirements are that information is transmitted reliably and in a timely manner.

Rodger Hosking Pentek, now part of Mercury

Open architecture embedded systems for military/aerospace applications have always relied on mezzanine or daughter cards to provide flexibility and modularity because they are very effective in handling the large variety of I/O functions required. Thanks to widespread adoption of industry standards defining these mezzanine products, carrier boards are able to accept mezzanine boards from a wide range of vendors, each specializing in niche technologies and interfaces.

VITA 49: The future of software radio - Blog

January 30, 2018

Rodger Hosking Pentek, now part of Mercury

The use of software radio technology has spread to almost every commercial, consumer, government, industrial, and military platform across the entire radio frequency spectrum during the technology's 25-year lifespan. Innovations in data converter technology, DSP devices, system interconnects, processors, software, design tools, and packaging techniques have improved performance levels and reduced the size, weight, and power consumption of software radio systems. However, the rapid surge in software radio applications spawned ad hoc, proprietary interfaces between the elements in these systems.

Rodger Hosking Pentek, now part of Mercury

Advances in optical interface technology boost performance levels to help meet increasing data rates and signal bandwidths. New specifications define how to deploy these optical links within open industry standards, affording improved interoperability and supporting future upgrades. Offering many advantages over traditional copper connections, optical links will boost data rates, improve signal integrity and security, and greatly extend distance between system components.

Fire and finish: The middle of the kill chain - Blog

December 22, 2017

Ray Alderman VITA Standards Organization

WARFARE EVOLUTION BLOG: As stated in previous articles, we need to reduce the complete kill chain down to 10 minutes or less, according to General John Jumper. So, all new systems and weapons must fit inside the kill chain somewhere (find, fix, fire, finish, feedback). And, they must speed things up significantly. We also established that the latest radar, sonar, SIGINT, IMINT, and other sensor systems fit in the find and fix phases. Now, it?s time to take a look at some of the latest developments going into the fire and finish phases.

Artificial intelligence (AI) and artificial stupidity (AS) - Blog

October 31, 2017

Ray Alderman VITA Standards Organization

WARFARE EVOLUTION BLOG: Isaac Asimov first published the three laws for super-intelligent robots in 1942, and we are ignoring them. Although Department of Defense (DoD) directive 3000.09, dated November 2012, says that a human must always pull the trigger or press the button on our weapons, we violated that when we created the Phalanx CIWS and the Aegis missile defense system, although those weapons are defensive. Now, everybody with a lot of money, or a lot of education, is claiming that Artificial General Intelligence (AGI) will take us to a ?singularity,? sometime between 2020 and 2040, where machines become exponentially smarter than humans. At that point, the machines and killer robots will eliminate humans and take over the world.

The future of Ethernet - Blog

ETHERNET EVERYWHERE BLOG: In my last blog, I took a look at the history of Ethernet. It was fun to look back at history, however it is more important to look at the future. With Ethernet becoming the ubiquitous connectivity standard for service providers, enterprises, and military applications, we are letting go of proprietary networking technologies and heading directly in to industry standard networking based on Ethernet.

Find and fix: The front-end of the kill chain - Blog

Ray Alderman

WARFARE EVOLUTION BLOG. I can speak to this topic with some level of experience. My old military intelligence unit, Army Security Agency (ASA) was the military arm of the National Security Agency (NSA). Our primary mission was to find, identify, fix, and track every significant military unit on the planet, including both our enemies and our allies. As Sun Tzu is credited with saying (or maybe it was Machiavelli, or Petrarch, or Michael Corleone): "Keep your friends close, and your enemies closer."

Additive manufacturing, and more specifically metal additive manufacturing (or metal 3D printing), is changing the manufacturing industry by lifting some of the design constraints inherent to traditional processes. Many industries are benefitting from this technology including the defense electronics world, where lattice structures have been applied to single-board computer (SBCs) assemblies to reduce weight while maintain performance and ruggedization requirements.

Aloha! Ethernet: The history of Ethernet - Blog

ETHERNET EVERYWHERE BLOG: So, to get a little retro on everybody, I thought I?d take a step back in time and have a fun look at the history of Ethernet. A couple of months ago, Ethernet actually celebrated its 44th anniversary. That?s right. Ethernet was developed back in 1973 and today, 44 years later, it is becoming THE ubiquitous local area networking (LAN) technology in addition to wide area networking (WAN) and now even infiltrating storage area networking (SAN).
