Radar

Engineers at UC Davis have developed a new radar sensor that can pick up movements just 100th the width of a human hair. Better yet, the sensor itself is only the size of a sesame seed and is energy efficient.

Saab's new Ultra-Lightweight Camouflage Screen not only lets soldiers blend into the foliage and blocks infrared to foil heat seeking sensors, but it also hides them from radar sweeps, while still letting them receive GPS signals and radio communications.

A WWII bunker in England has been transformed into a remarkable vacation home. UK studio Corstorphine & Wright worked to retain the original character of the bunker while adding a "bomb blast" glazed opening to provide superb views of the coastline.

There are now a number of ebikes equipped with radar systems which warn riders of vehicles approaching from behind. If your bike isn't among those, you can now change that by slapping on Garmin's Varia eRTL615 radar/tail light module.

New evidence has emerged in the debate about whether there’s liquid water on Mars. In a study led by the University of Cambridge, scientists examined the topology of Martian ice sheets and found signatures that match subglacial lakes here on Earth.

It was seven years ago that we first heard about Garmin's Varia Radar tail light, which warns cyclists of vehicles approaching from behind. After adding smartphone compatibility in 2020, Garmin has now put a camera in the device.

A new type of radar can measure objects down to centimeters. The new technique uses a photonic system to generate much higher bandwidth signals, enabling radar that can detect smaller objects, and even monitor patient vital signs in hospitals.

Cannondale's Synapse has always been a fairly well-regarded road bike, but the latest version sports a little something extra. It's called the SmartSense system, and it's designed to help keep riders from being struck by cars.

Many cars are now equipped with pedestrian-detecting radar systems, but those systems can still be blocked by obstacles such as buildings or other vehicles. A new setup is intended to get around that problem, by taking the radar to the streets.

Israeli company Vayyar says it can replace a bunch of car interior sensors with a single, hidden "4D radar" unit the size of a credit card, saving significant development costs while unlocking a range of upcoming safety features.

Self-driving cars typically use both LiDAR and radar to detect obstacles on the road ahead, yet neither system is adept at identifying vehicles through fog. Now, though, engineers have discovered that radar is good at the task if it's "doubled up."

Five years ago Garmin first introduced its Varia Radar system, which warns cyclists of cars approaching from behind. The company has now announced an updated version, that offers a couple of key improvements over the original.
