RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its
primary purpose was to provide me with ready access to commonly needed formulas and reference
material while performing my work as an RF system and circuit design engineer. The Internet was
still largely an unknown entity at the time and not much was available in the form of WYSIWYG

Northrop Grumman's AN/AAQ-37 Distributed Aperture System (DAS) RF Cafe
Videos for Engineers
are a few realms remaining where America's lead has not been surrendered to the world; among them are military and
aerospace systems. The technological prowess applied to these tactical and strategic systems are the most advanced
anywhere. Yes, there are areas where other countries have the lead, but despite the best efforts of some of our
scumbag politicians, overall our advantage is unquestionable. It has never been so that if you are nice to
everybody, then everybody will be nice to you. Any country or bloc that lets down its guard will eventually be
attacked and dominated by an aggressor. Sorry, it's just the way it is on Planet Earth. That said, I am glad to
see promotions (call it propaganda if you like) for systems like Northrop Grumman's
Aperture System (DAS) for airborne platforms like the F-35 Joint Strike Fighter. It assimilates data from a wide
array of sensors spread across the aircraft structure to generate a comprehensive situational awareness for the
pilot. In fact, DAS has the capability to share data with other craft in its company to enhance group
effectiveness. Combined with advanced smart missiles, search and destroy, evade and escape, and dogfighting
missions, DAS will provide an even higher probability of success.
Among the capabilities of DAS are
missile detection and tracking, launch point detection, situational awareness, IRST (infra-red search and track )
& cueing, weapons support, and day/night navigation. Watching the video is like seeing the trailer of a
sophisticated video game. If you doubt whether these types of systems can really perform the kind of actions shown
here, look around on YouTube for actual footage of airborne engagements made in the last few years in the Middle
East. The surgical precision of the missile strikes are utterly incredible.
As unpopular as the claim might be to some, the technology to enable an acquire, lock-on, and shoot-down
capability on maneuverable airborne targets got its start in the Strategic Defense Initiative (SDI, aka "Star
Wars") program that began in the 1980s. Despite large efforts by the media and lawmakers to discredit and
undermine the efforts, we now have viable systems with real world proof of capability. If we want to continue to
be a free people, the work must not be allowed to be stopped.
