The US Air Force has upgraded its test facility to conduct wideband bistatic imaging and radar cross-section measurements of full-sized aircraft. The Bistatic Coherent Measurement System (BICOMS) provides a mobile system for bistatic as well as monostatic tests, improving efficiency and accuracy.
Ground-penetrating radar is used to map large areas and determine snowfall patterns, providing a record for comparison with climate models. The technology can accurately date ice layers, which is essential for studying glacial cycles and changes in atmospheric chemistry.
Researchers in Missouri have designed a bullet that emits a powerful radar pulse as it grinds to a halt, allowing for the detection of landmines without stepping on them. This technology can help geologists survey for oil, minerals, and other buried natural resources, and may be used to locate mines in remote areas.
Recent progress in Over-The-Horizon (OTH) radar technology is reviewed, including advancements in detection and tracking systems. Key findings include improved capabilities in clutter-dominated environments and the development of advanced algorithms to mitigate distortion mechanisms.
The RADARS study found rectal diazepam gel to be effective in reducing seizure frequency and improving outcomes for patients with acute repetitive seizures (ARS). Administered by caregivers, the treatment demonstrated minimal potential for serious adverse events, making it a cost-effective option.
A computer program developed at Ohio State University has enabled the U.S. Navy to design a new system of antennas that reduces radio interference and makes its destroyers less visible to enemy radar. The NEC-BSC program traces the path of electromagnetic waves and allows for the design of lighter materials and improved radar performance.
Scientists are using Synthetic Aperture Radar (SAR) technology to study subtle phenomena such as volcano deformations before eruptions and gradual buildup of stress over years. SAR is also being used to map the flow of ice sheets and glaciers, and gather data on land subsidence issues related to fluid withdrawal.
Researchers at University of Illinois set new record for radar cross-section calculation, a measure of aircraft visibility to radar. The achievement uses advanced software and fast multipole method algorithm, reducing computation time and memory requirements.
New Arecibo radar images show no signs of ice in permanently shadowed areas at the moon's poles. Researchers believe rough surfaces from impact craters may be responsible for observed reflections instead.
Researchers at Penn State have discovered that millions of tiny, previously undetected invaders enter the Earth's atmosphere daily. These micrometeorites are thought to be leftover material from the formation of the solar system and carry significant energy, potentially damaging satellites and spacecraft.
A new cockpit display system being developed at Michigan Technological University aims to alert pilots of nearby aircraft and reduce mid-air collisions. The system uses passive radar and GPS squitter signals to provide real-time traffic information, greatly improving flight safety.
A Colorado State University researcher has developed a real-time radar system that can identify airborne objects even in dense air traffic, improving air safety and efficiency. The technology was tested successfully and is set to be installed in military aircraft, with commercial applications also being pursued.
Researchers will explore innovations in mine detection using microelectronic chemical-sniffing 'nose', ultrasound, and unique mathematical aids. The projects aim to detect buried military booby traps that kill or maim innocent noncombatants.
Wake vortices, created by large commercial aircraft, will be studied at Baltimore Washington International Airport (BWI) to develop a reliable detection system. The system aims to increase airport safety by providing controllers with observed vortex location and intensity information.
The Arecibo Observatory has completed a $25 million upgrade, increasing its sensitivity by a factor of about 20 for radar studies of the solar system. The new system will allow scientists to listen into cellular phone calls on Venus and detect steel golf balls at moon distances.
