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 photo of two operators on an aircraft using the Laboratory's Airborne Radar Testbed to command a radar to test and demonstrate intelligence, surveillance, and reconnaissance radar concepts.
radar
An aircraft outfitted with an advanced open-architecture radar system provides a platform for testing new radar technology.
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.

communications
High-altitude balloons used as beyond-line-of-sight relays would provide communications nodes if satellite communications could not offer coverage in contested environments.
Ray tracing that simulates wave propagation is used to build performance models for high-frequency radar and communication systems.
satellites
New algorithms improve the resilience of satellite and RF systems to impacts from space weather.
