Avionics upgrades enhance situational awareness for military pilots - Story

March 05, 2014
Military avionics retrofits to aircraft such as the B-1 Bomber are leveraging powerful commercial processors and high-speed networking in a distributed architecture to enable future capability upgrades. Meanwhile, safety concerns related to degraded visual environments are driving synthetic vision designs for rotary wing platforms.

New capabilities on the way for airborne maritime surveillance radars - Story

January 29, 2014
Airborne maritime surveillance radars play a central role in the global homeland defense of more than 315,000 miles of worldwide coastline. While considered state-of-the-art, these radars continue to evolve to meet military customers' needs for persistent surveillance, automation, and continued tracking of targets as they move from sea to land.

GPS: Smaller, faster, jam-proof, and nearly everywhere - Story

December 17, 2013
Missile systems, Unmanned Aerial Vehicle (UAV) payloads, soldier radios, and other applications are seeing the benefits of miniaturization and enhanced performance in Global Positioning System (GPS) technology. However, GPS designs also require more elaborate anti-jamming techniques such as combining GPS with Inertial Measurement Units (IMUs) to combat new, sophisticated threats. Meanwhile, DARPA researchers continue to reduce GPS footprints as they combine a tiny IMU and timing capability on one substrate.

Evolving radio technology: SDR to cognitive radio - Story

October 09, 2013
Software-defined radio is no longer a military-only technology, as it has evolved beyond the now-defunct Joint Tactical Radio System (JTRS) program, can be found in commercial and defense applications worldwide, and is essentially a solved problem. Meanwhile, a big remaining challenge is the finite amount of available spectrum. Dynamic spectrum management is needed to navigate what is left and cognitive radio is seen as the technology that will make that possible.
