Abstract: Traditional active radars transmit a powerful electromagnetic pulse and record the echo's delay time and power to measure target properties of interest, such as range, velocity, and ...
Active sensing encompasses the use of a transmitter and at least one receiver to measure (sense) the transmission or scattering properties of a medium at radio frequencies. In transmission ...
Permafrost on the Qinghai-Tibet Plateau (QTP) undergoes significant thawing and degradation under climate warming. Ground deformation is a key indicator of permafrost degradation, which can be ...
ETH researchers are using radar to scan the snow and ice on the Jungfraujoch. Sometimes, scaling an icy peak is the only way for scientists to fully understand satellite data. With mist obscuring the ...
The evolving landscape of unmanned aerial systems (UAS) creates significant societal and logistical changes, impacting defense, national security, disaster response and even package delivery. For the ...

Ground-penetrating radar found the Petra tomb before a single shovel touched the rock
Researchers from the University of St Andrews located a hidden tomb beneath Al-Khazneh, the iconic Treasury facade at Petra, ...
Since the early 2000s, ultra-wideband (UWB) technology has gradually found its way into a variety of commercial applications that require secure and fine-ranging capabilities. Well-known examples are ...
MOUNTAIN VIEW, Calif. – The National Reconnaissance Office will invite companies to propose remote sensing capabilities on an ongoing basis. In the past, the agency responsible for designing, building ...
The evolution of automotive safety is moving from the exterior to the interior, opening a new frontier: in-cabin sensing. Its emergence marks a shift from passive vehicle shells to active systems ...
[tpsully]’s Radar Glasses are designed as a way of sensing the world without the benefits of normal vision. They consist of a distance sensor on the front and a vibration motor mounted to the bridge ...
