Compact radar takes an inside view

The human eye cannot see through wood, paper, or plastic. But a compact radar with a modular design now makes it possible to see the invisible: The millimeter wave sensor penetrates non-transparent material. It transmits ...

NASA to launch ocean wind monitor to space station

(Phys.org)—In a clever reuse of hardware originally built to test parts of NASA's QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean-surface ...

Nanoscale impulse radar measures depth of snow and ice

Snow is the be-all and end-all for alpine ski resorts. Now a tiny sensor has been developed to determine how much cold gold there is on the slopes and how much more should be produced. The sensor is based on Norwegian radar ...

A low-cost, finger-nail sized radar

European researchers have squeezed radar technology into a low-cost fingernail-sized chip package that promises to lead to a new range of distance and motion sensing applications. The novel device could have important uses ...

Radar technology: Now housed within thumbtack-sized chip

Today's parking assistant systems enable drivers to safely park their cars even in the narrowest of gaps. Such sophisticated parking aids, and also manufacturing robots which, to move about in unknown environments, require ...

NRL RAIDS experiment advances ionospheric remote sensing

Naval Research Laboratory scientists have obtained a first-ever measured altitude profile of a dim extreme-ultraviolet terrestrial airglow emission that provides vital information needed to test and improve the accuracy of ...
