It's often said that a soldier's greatest weapon is his head; now, the U.S. Army plans to sharpen that weapon, installing radar in troops' combat helmets, upgrading one of the oldest pieces of infantry armor into an effective tactical device.
The Helmet Mounted Radar Program aims to provide a near-360-degree field for Moving Target Indicator (MTI) radar sensors that is low-power and can detect a moving threat as far out as 25 meters. The sensor should be integrated into the combat helmet and weigh less than two-and-a-half pounds, with less than a pound mounted on the helmet itself.
Today's stealth fighters, such as the F-22 Raptor, may do pretty well in concealing their radar signature, but mathematicians say that a new active cloaking technique could someday generate electromagnetic fields to hide submarines from sonar, or even protect buildings from earthquakes.
In modern warfare, where missions are sometimes over in minutes, a blind enemy is a defeated enemy. The electromagnetic pulse from a nuclear weapon detonated miles aboveground would zap an army’s surveillance equipment, but not without causing heavy collateral damage. Instead, a new Air Force tool will fry electronics using high-power microwaves emitted by an unmanned aerial vehicle (UAV).
Debuted during the Home Run derby, the ball-tracking tech uses advanced data processing to superimpose on your screen where a ball will land immediately after it leaves the bat, just like in the video games
As if a night filled with 480-foot home runs wasn’t exciting enough, ESPN introduced its much-hyped Ball Tracker technology during Monday's Home Run Derby, giving balls a digital comet trail that indicated whether or not it could clear the fences.
While superimposing graphics in post-processing has been around longer than steroids, the system unveiled last night has some truly cool tech powering it, relying on Doppler radar to instantly track and predict the ball's path in real time, just 400 milliseconds after it leaves the bat.
Southern Californians may be living on borrowed time. At least two sections of the notorious San Andreas Fault, a hotbed of tectonic tension, are apparently overdue for a huge earthquake that could devastate Los Angeles County or San Francisco. Though they can neither prevent nor pinpoint it, scientists would like to get as much information as they can as to where and when the next "Big One" could happen. Increasingly, they're turning to air and space to learn what's happening 10 miles underground.
A new radar plane developed at NASA's Jet Propulsion Laboratory is the first American system designed to map earthquake hot zones.
Thanks to threats from North Korea, an experimental missile shield and radar system may be deployed to Hawaii before testing has been completed. After North Korea’s recent nuclear test and vague threats of launching another Taepodong-2 missile towards Hawaii, the Pentagon has decided to rush the still-in-development Army Terminal High-Altitude Air Defense missile systems and the SBX x-band radar into action. Although the technology has existed for many years it may finally get its first test in real-world conditions.
What does the past look like from 200 miles up? A new generation of archaeologists has found that the history of civilization may look far clearer from the top of the atmosphere than it does from the bottom of a dig

If it weren’t for the landmines, Lingapura would be a great place to dig. For part of the 10th century, this pocket of northwestern Cambodia was the capital of the famed Angkorian empire, a sprawling city studded with homes, irrigation channels, and more than 1,000 temples crowned with stone lingam, or phalluses. But ever since Pol Pot and the Khmer Rouge dotted Cambodia with millions of landmines in the 1970s, Lingapura’s ruins have sat mostly untouched.

A radar device aboard ESA's Mars Express orbiter has allowed scientists to peek beneath the surface from afar, and the success with this research is now prompting them to think up other spots in the solar system that would be ideal for this sort of examination.

In the aftermath of the Feb. 6 tornado, scientists at The University of Alabama, Huntsville have been analyzing radar images of the event, searching for signs that might help them issue faster warnings in the future. The radar signature from debris sucked up into the air is so distinctive that the group thinks it may be able to develop an automated detection system. Essentially, theyd program computers to automatically pick out these signs in the data, and raise a flag immediately.
PopSci's GM hunts for lost golf balls with a new radar gadget

We gadget editors were intrigued by the idea of RadarGolf, a new device that allows players to home in on special balls equipped with radar chips, but none of us actually knows how to play golf. Luckily, our esteemed general manager, Rob Novick (handicap 17), was willing to take a swing at reviewing it for us. Here's what he had to say:
Radar, lasers, wireless radio networks and other embedded tech will enable our cars to sense faraway traffic and stop accidents before they happen. But who will be in the driver’s seat?

I’m driving through eastern France, the blip-blip of the lane markers zinging backward through my peripheral vision at about 90 mph. I check the mirrors: nothing there. Pretending to doze off, I let the car drift gently to the left. Just as it begins to veer over the dotted line, the left side of my seat vibrates, activated by an infrared sensor looking at the road paint. Meander right, and it’s my right thigh that gets the warning.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
