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 ...
The test was flown in November 2014. [26] The pod operates independently of the aircraft's systems, automatically responding to identified threats. One unique aspect of the NGJ is that its AESA array combines EW, coms, radar, and signals intelligence. AESA is known to perform EW and radar, but also handling SIGINT and serving as a ...
On December 2, 2016, KWTV unveiled "NextGen Live", a dual-polarization Doppler weather radar designed by Baron Services, which conducts atmospheric scans at 6 RPM—a faster rate than the radars operated by its three main competitors, KFOR, KOCO (which both have their own on-site radars) and KOKH (which has a radar system that relays NEXRAD ...
R8 Radar/Laser Detector. The R8 is Uniden's top-of-the-line offering. It can identify threats coming from all four directions thanks to its dual antenna, and you get notified via voice alerts.
The information from the signal is sent to an Air Traffic Control tower, or a Radar Approach Control (RAPCON) with a digital tag that describes the location, heading, and speed at which the aircraft is moving. The overall operation of the ASR-11 is similar to that of the ASR-9, with relatively few differences between the two radar systems.
The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. [1] [2] The system offers instrumented detection at ranges on the order of 200 to 250 nautical miles (370 to 460 km; 230 to 290 mi) and has a wide variety of interference and clutter rejection systems.
In the past, radar AGC was electronically controlled and affected the gain of the entire radar receiver. As radars evolved, AGC became computer-software controlled and affected the gain with greater granularity in specific detection cells. Radar multipath echoes from a target cause ghosts to appear.
A popular Washington sushi restaurant has closed two of its locations after a viral TikTok video posted by influencer Keith Lee sparked food safety concerns.
