ORNL buildings researchers, from left Philip Boudreaux, Rui Zhang, Stephen Killough and intern Mercy Sammy, demonstrate how a microwave radar system can detect moisture in a wood panel. For homeowners ...

Computational imaging and microwave radar systems represent a synergistic research domain where advanced signal processing, innovative hardware architectures, and algorithmic developments converge to ...

Pedaling through a traffic intersection on a bicycle sometimes doesn’t leave enough time to ride through the green light before the signal turns red. So a few cities in California are testing a ...

Radar, at its simplest, involves sending out pulses of radiation that reflect off an object. The reflected signal is detected, and the time of flight is measured. The time of flight is then translated ...

I recently picked up a couple of microwave motion sensor radar modules. You have seen (and perhaps tried) it before. This post is about the HFS-DC06 (DC5V/5.8GHz) Microwave Radar Sensor Switch Module!

Detection using today’s microwave sensors has some advantages. Unlike traditional passive infrared motion sensors, most microwave sensors can distinguish between moving and static objects, and objects ...

In the days before integrated circuits became ubiquitous, providing advanced functionality in a single package, designers became adept at extracting the maximum use from discrete components. They’d ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. We’ve had radar for nearly a century. An understated piece in ...
