RF & Microwave

Over the past 60 years, NASA scientists and engineers have developed many advanced technologies and processes. But NASA has also partnered with industry, using commercially available products to complete its missions. Here, some of those companies join NASA in celebrating these collaborative successes.

Electrical power lines pose a serious crash hazard to helicopters and other air-based vehicles, especially small aerial vehicles such as unmanned aircraft systems (UAS). This is because power lines are so widespread, hard to see, and strung at roughly the same height above the ground at...

NASA's Langley Research Center has developed a novel fine interpolation technique that is useful in signal processing for applications in lidar, sonar, radar, and similar modalities. The interpolation technique uses...

Microwave antennas deployed for spaceborne radiometers are diffraction-limited, with typical beam efficiency of about 90%, and provide relatively poor selectivity against radiation from celestial bodies (Moon, Sun, galaxy) when they are...

A recent Tech Briefs TV video demonstrated an artificial-intelligence system developed by MIT researchers. The "RF-Pose" teaches wireless devices to sense people's movement, even from the other side of a wall. See the system in action.
