Until recently phased array radar has been very expensive, used only for military applications where the cost of survival weighs in the balance. With the advent of low-cost microwave devices and ...

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 ...

Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...

Alfred Lee Loomis in his Tower House lab, Tuxedo Park, NY. "The Secret of Tuxedo Park" kicks off another year of American Experience documentaries on PBS Tuesday, January 16, at 9pm ET (check local ...

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 ...

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 ...

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 ...
