An illustration of two self-driving cars detecting nearby objects and sharing sensor data using the same radio-frequency band.
RF technology
New waveforms enable efficient spectrum sharing between radars sensing moving objects and wireless communications systems transmitting data.
A schematic of a burning building with firefighters, firetrucks, and uncrewed aerial vehicles on the scene. Arrows link between them, each within concentric circles, to signify a radio-frequency network.
navigation systems
With the goal of enabling navigation in environments where GPS is unavailable or unreliable, researchers are developing algorithms to fuse information across a network of small, low-power radio-frequency devices.
A researcher stands on a laptop. In front of him are a few small radios, and a large projector screen showing data.
RF technology
A deployable navigation network of small, low-cost radio transponders can help track the locations of first responders during rescue operations.
A photograph of the Airborne Sensor Test Bed.
A uniquely modified jet is an important asset for making important measurements of tactical aircraft.
three people stand on a big dirt pile, outside, with blue sky in the background. One researcher is holding a laptop, which another looks at. The third person is holding a remote, controlling a robotic vehicle also on the dirt pile.
disaster relief
Our see-through-wall sensor is a lightweight, portable technology that peers through rubble and debris of a disaster site to detect survivors.
