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 ...

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 ...

This article explains an upgraded smart solid-state AC switch system that uses microwave Doppler radar instead of traditional ...

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 ...

A group of scientists from China may have created a stealth material that could make future fighter jets very difficult to detect by some of today’s most cutting-edge anti-stealth radar. The ...

In quantum entanglement, two or more particles are seemingly linked in a state of mutual instantaneous influence, no matter how far apart they are. And its not just quantum computers that make use of ...

An evaluation kit with a fully operational 24GHz radar movement detector is being sold by Aspen Electronics. The K-LD2 evaluation kit has been developed by RFbeam Microwave, a German supplier of ...

The microwave has evolved into one of the most popular household appliances in the world, but few people know that it was invented entirely by accident. In 1945, Percy Spencer, an American self-taught ...

Microwave absorbers are a kind of material that can effectively absorb incident microwave energy to make objects invisible to radar. Recently, as radar detection devices have improved, scientists are ...
