Shakespeare’s missing skull – the tech behind the investigation

You've probably already heard that a recent investigation into Shakespeare's tomb for a documentary on the UK's Channel 4 revealed that the bard's skull has likely been removed from his tomb. What you may not know, however, is exactly how that was determined. We caught up with one of the researchers to find out more about grave-glimpsing with ground-penetrating radar.Read More

New stealth material could defeat latest radar systems

Stealth aircraft like the F35 fighter generally rely on high-tech absorption materials and unusual geometries to scatter, deflect, and sponge up incoming radar signals. These techniques are exceptionally good at masking a vehicle's shape and size, particularly when swept with side-scanning radar. However, with lower-frequency, directed anti-stealth radar-targeting systems being developed, these surfaces prove much less able to hide an object. To help address this, a team of Chinese scientists has developed a thin electronic material that sheaths an object and effectively absorbs radar signals over a wide range of frequencies.Read More

Cotlo's Corvus smart bike knows when cars are coming from behind

Even if motorized bicycles turn you off, perhaps you still appreciate some of the electronic bells and whistles that are included on many e-bikes. If that's the case, then a "smart bike" might be more to your liking. One of the latest to catch our eye is the Cotlo Corvus, which features a car-detecting rear radar system and a built-in OLED display. We came across a prototype at Interbike 2015, and got the goods.Read More

Garmin's Varia Radar warns cyclists of traffic approaching from the rear

Garmin gave hope to many a floundering tech startup's CEO earlier this year when it purchased Ikubu Ltd in the wake of a crowdfunding campaign that came up short. Though the company failed to capture the imagination of the Dragon Innovation crowdfunding community, Garmin liked the cut of Ikubu's jib, so it snapped the company up with a view to bringing its rear-facing bike radar system to market. Now, the electronics giant has unveiled the finished, more polished product dubbed Varia Radar, which also integrates with Garmin's Edge cycle computer.Read More

Combination radio/radar imaging produces stunning view of Venus

A team of astronomers combining radio data from the Green Bank Telescope, West Virginia, and data from the radar transmitter at the National Science Foundation's Arecibo Observatory, Puerto Rico, have compiled a stunning new view of Venus. Often described as Earth's twin due to its similar proportions, capturing high quality images of the inhospitable planet has traditionally been a challenging prospect thanks to extreme atmospheric conditions. However, by combining observations from the instruments to create a more complete picture of Venus, astronomers can begin to observe how this enigmatic celestial object evolves over time.Read More

Garmin may begin offering radar systems for bikes

Even when a crowdfunding project doesn't meet its financial goal, it can still turn out to be a success. A case in point is iKubu Ltd's Backtracker, a car-detecting low-power radar system for bicycles. Although the South African startup's fund-raising campaign on Dragon Innovation didn't work out, electronics giant Garmin has now bought the company. Read More

BAE Systems develops advanced radar for Eurofighter Typhoon

BAE Systems is in the process of developing and testing a next-generation radar system for the Eurofighter Typhoon. The Captor E-Scan, fitted in the nose-cone of the fighter, boasts a number of improvements over other Active Electronically Scanned Arrays (AESAs), including a wider field of regard and the provision of advanced electronic warfare protection.

Sentinel-1A Earth-monitoring satellite begins operational life

Sentinel-1A, the first of a planned fleet of ESA satellites central to the European Commission's Copernicus environmental monitoring program, has begun its operational life. Following the completion of its commissioning and transfer to the team in charge of its operation, users now have access to data from the satellite, which will provide all-weather, day and night radar imaging for land and ocean services.Read More

Automotive

Mercedes-Benz unveils Blind Spot Assist technology for trucks

Trucks today are big and getting bigger, and even with cameras and superior spatial awareness, the operators of these leviathans can never be totally aware of potential collision hazards, especially when turning. To help alleviate this problem, Daimler, the truck division of Mercedes-Benz, has introduced a radar-based system that alerts the truck driver of imminent collision danger from anywhere on the entire unobservable portion of the vehicle.Read More
