The National NEXRAD Radar network operates with S-band frequencies. Before implementation of this system, C-band frequencies were commonly used for weather surveillance. In the United States, the 3.55 to 3.7 GHz band is becoming shared spectrum under rules adopted by the Federal Communications Commission in April 2015 as a result of the ...
NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
Marine radar. Animation of typical rotating X band marine radar antenna on ship. It radiates a narrow vertical fan-shaped beam of microwaves perpendicular to the long axis of the antenna, horizontally out to the horizon. With each rotation the beam scans the surrounding surface. Any ships or obstructions reflect microwaves back to the antenna ...
The S-band and X-band sensors will also share functionality, including radar navigation, periscope detection, and missile guidance and communication. SPY-6 is intended as a scalable system, with each sensor array assembled from Radar Modular Assemblies (RMA), self-contained radar modules.
SMART-S Mk2[ 2][ 5][ 4] (Signaal Multibeam Acquisition Radar for Tracking, S band Mk2) is a naval medium to long-range air and surface surveillance multibeam passive electronically scanned array 3D radar designed by Thales Nederland, [ 6] formerly Hollandse Signaalapparaten (Signaal). While the original SMART-S radar was only produced in small ...
A counter-battery radar or weapon tracking radar is a radar system that detects artillery projectiles fired by one or more guns, howitzers, mortars or rocket launchers and, from their trajectories, locates the position on the ground of the weapon that fired it. [ 1]: 5–18 Such radars are a subclass of the wider class of target acquisition ...
The Sea-Based X-Band Radar ( SBX-1) is a floating, self-propelled, mobile active electronically scanned array early-warning radar station designed to operate in high winds and heavy seas. It was developed as part of the United States Department of Defense Missile Defense Agency's (MDA) Ballistic Missile Defense System.
The NASA-ISRO Synthetic Aperture Radar, or NISAR satellite, will use advanced radar imaging to map the elevation of Earth's land and ice masses four to six times a month at resolutions of 5 to 10 meters. [ 9] It is designed to observe and measure some of the planet's most complex natural processes, including ecosystem disturbances, ice-sheet ...
