You might think you can dodge every speeding ticket with your dashboard radar detector, but you’d be surprised. Here’s how radar detectors actually work and why you’re probably better off just going the speed limit.
If you want to fly under the radar, you could do with a sheet of this material. Using a series of liquid-metal absorbers, the new film can soak up radar in order to cloak whatever it happens to be covering.
This grainy black-and-white image may not look like much, but it’s a record-breaker. A radar scan acquired by satellite and beamed back to Earth by laser, it allowed the European Space Agency (ESA) to identify ships off the coast of Brazil in less than 18 minutes—without any satellite ground stations nearby.
It may look like any other picture of a silicon chip, but this one’s rather special: It’s the centrepiece of a new 94 GHz radar system being developed by the European Space Agency, that will transform radar systems in space missions.
Because it has a goal! But a different kind of goal to the ones found in soccer: instead, it’s one to put American astronauts on Mars.
BAE Systems’ high-tech 3D radar system called Artisan has been successfully installed to the Royal Navy’s future aircraft carrier, HMS Queen Elizabeth.
This photo looks like a still from a scifi movie about cyborgs. In fact, it shows an operations specialist monitoring radar during a general quarters drill aboard the 10-year-old guided-missile destroyer USS Farragut (DDG 99). [Mass Communication Specialist 3rd Class Jackie Hart/U.S. Navy]
Chernobyl is obviously well-known for one particular thing, but as it turns out, the town is hiding things other than two-headed squirrels.
A couple years ago, NASA and DHS unveiled a portable radar unit based on technology used to monitor spacecraft. This radar unit, though, would be used closer to home—to find people burried under rubble. In the first real-world demonstration of its use, the device helped save 4 men trapped under earthquake rubble in…
Birds have a bad habit of flying directly into big machines, like planes or wind turbines. This phenomenon, dubbed “birdstrike,” usually ends, well... badly for our feathered friends. But the key to saving these doomed birds could be another bird.
A new device that can "see" through walls using radio waves started stirring up privacy concerns in a federal appeals court just last month. And it's about damn time; according to a recent report from USA Today, over 50 law enforcement agencies have secretly been using the new radars for the past two years.
What if you had a personal cameraman perfectly tracking your perfect 900-degree spin as your dreams of become Tony Hawk came true? The Move 'N See Pixio wants to robotically assist you.
Back on November 23rd, the Pico do Fogo volcano on Cape Verde's Fogo island erupted. This image shows how that incident looked when it was captured by the Sentinel-1A satellite's radar sensors.
This radar image of Tokyo was acquired by the European Space Agency's Sentinel-1A satellite earlier this year. The data is so accurate that it can monitor ground movements down to a few millimetres—which helps urban planners know where they can and can't build. [ESA]
Even when the elderly are being tended to by a caregiver, it's almost impossible to keep an eye on them 100 percent of the time. So a Japanese company has developed a pair of LED light bulbs featuring built-in laser-based radar to track the movements of someone in its vicinity, and automatically send alerts when they…
In 1940, less than a year after blitzkrieging its way through Poland and the rest of Western Europe, the Nazi army set its sights on the UK and commenced a vicious bombing campaign targeting the nation's major cities. Luckily, the British Royal Air Force saw this threat coming and cleverly deployed a series of radio…
Was it a bird? A plane? A tornado cell? Nope. The huge, slow-moving cloud picked up on radar in Illinois and Missouri last week was nothing anyone expected. The US National Weather Service reports it was actually a swarm of millions of monarch butterflies—which have been disappearing at alarming speeds over the past…
From afar, wind turbines look like small toys spinning lazily in the wind. But get up close, and you realize what huge structures they really are: hundreds of feet tall, blade tips slicing through the air at over 100 mph. And these wind turbines can really scramble airport and weather radars. To solve the problem,…
When Hurricane Arthur made landfall on the North Carolina coast last weekend, it was the strongest hurricane to strike the United States since Hurricane Ike hit Texas in 2008. The storm was downright impressive visually, and these gifs document the latent beauty of nature's power.
As the number and variety of air, space, and surface-based threats to our naval fleets continue to proliferate, defending against them all is getting harder and harder. But equipped with this new unified threat detection system from Raytheon, our Arleigh Burke-class destroyers will know what's coming from 30 times…
