Seeing Through The Fog (And Dust And Snow) Of War

Degraded visibility—which encompasses diverse environmental conditions including severe weather, dust kicked up during takeoff and landing and poor visual contrast among different parts of terrain—often puts both the safety and effectiveness of tactical helicopter operations at risk.

    4 Electronic Design Requirements Of The System-Integrated Soldier

    Perhaps most famously portrayed in Robert Heinlein’s Starship Troopers (1959), the idea of the “future soldier” has been around for decades. As rehashed in countless science fiction films and video games, the stereotypical future soldier is equipped with a protective exoskeleton, enhanced sensory equipment, seamless communication systems, and advanced weaponry. While the concept once seemed implausible, there are many real-world projects under way focused on realizing those seemingly fictitious warfighter capabilities — by integrating a plethora of diverse electronic subsystems into a cohesively operational suit.

    7 Noteworthy Technologies From IMS2014

    At the 2014 IEEE MTT International Microwave Symposium earlier this month, I had the opportunity to speak with the event’s general chair, Dr. Larry Dunleavy, about the state of the RF and microwave design industry. While he acknowledged that it is a time of relative uncertainty — due in large part to constrained military budgets and conservative fiscal forecasts for 2014 — he also pointed out that there are plenty of emerging markets where RF and microwave technology is making a significant impact. With the Internet of Things (IoT) driving innovation in burgeoning markets like automotive and healthcare  and the development of 5G pushing wireless technology to further heights, there was good reason for nearly 600 companies to flock to the IMS2014 exhibition in Tampa, Fla.

    EM De-Embedding Magic – Part 3: What Could Possibly Go Wrong?

    In Part 1, I described the EM analysis port calibration algorithm that I developed almost 30 years ago and has been in use in Sonnet ever since. At first glance, it might seem like the technique can be applied only to “lonely” ports — ports that have no interaction or coupling with any other nearby ports. In Part 2, I showed how the algorithm can be easily extended to calibrate and de-embed as many tightly coupled ports as needed. Yes, a couple equations are needed, but once you get familiar with them, the process is really easy to do. Everything works so well, one might think that nothing could possibly go wrong.
