We chose to focus on SDR waveforms because of their extraordinary promise for interoperability and efficient use of spectrum. With these benefits in mind, it’s especially satisfying to see the recent announcement from Lockheed Martin. They’ve delivered an Engineering Development Model (EDM) of their radio system to the USAF as a component of the Airborne & Maritime/Fixed Station Joint Tactical Radio System (AMF JTRS).
While this particular milestone focuses on the C-130J Super Hercules and the C-5 Galaxy, once delivered, the AMF JTRS will provide critical links between ground, naval and air forces. The system supports very secure (NSA Type 1) vox/data comm and interoperates across service branch boundaries. Of course, in these budget constrained times, it’s also crucial that the systems demonstrate compatibility with legacy comm equipment already deployed in the theaters of operations.
According to Mark Norris, vice president for Joint Tactical Network Solutions with Lockheed Martin’s IS&GS-Defense:
“This delivery of an official EDM Joint Tactical Radio hosting Link-16, coupled with the earlier delivery to the U.S. Air Force of a pre EDM supports platform integration risk reduction efforts for both C-130J and C-5 and further demonstrates the ability of a software defined radio to meet the evolving communications needs of our warfighters.”
The company’s press release also includes these choice bits of news: (emphasis mine)
“The AMF JTRS network will provide an order of magnitude improvement in allowing Warfighters in disparate areas to seamlessly communicate. To validate the difference, Lockheed Martin conducted warfighting simulations using the AMF JTRS variant being developed for aircraft and warships. Compared with existing communications gear, AMF JTRS delivers a significant gain in situational awareness and speed of command. In addition, JTRS networking waveforms provide an enormous increase in transmission capacity in any given period of time for vital targeting information and intelligence.

There we go. More efficient use of the spectrum and interoperability pay off with vastly superior situational awareness, speed of command, intelligence gathering and directing ordnance for maximum effect. That’s why we do SDR!
