Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. [1] Individual objects can be detected using the Doppler effect , which causes the received signal to have a different frequency from the transmitted signal ...
The 2013 Moore tornado was a large and extremely violent EF5 tornado that ravaged Moore, Oklahoma, and adjacent areas on the afternoon of May 20, 2013, with peak winds estimated at 210 miles per hour (340 km/h), killing 24 people (plus two indirect fatalities) [2] and injuring 212 others. [3]
Scheduled for 11 August, the raid was moved earlier by two days to avoid a five-day period of bad weather forecast to begin on 10 August. [189] Three bomb pre-assemblies had been transported to Tinian, labeled F-31, F-32, and F-33 on their exteriors. On 8 August, a dress rehearsal was conducted off Tinian by Sweeney using Bockscar as the drop ...
Inverse synthetic-aperture radar ( ISAR) is a radar technique using radar imaging to generate a two-dimensional high resolution image of a target. It is analogous to conventional SAR, except that ISAR technology uses the movement of the target rather than the emitter to create the synthetic aperture. [1] ISAR radars have a significant role ...
Synthetic-aperture radar ( SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [ 1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.
Temperatures for individual cities on the primary forecast map and temperature lists are suffixed with a one- or two-letter code, such as "t" for thunderstorms, referencing the expected weather conditions. The colorized forecast map was created by staff designer George Rorick (who left USA Today for a similar position at The Detroit News in ...
In August 2021, a contract was signed with Saab to modernize the Gripen fleet of the Hungarian Air Force. The radar will be upgraded to PS-05/Mk4 and the software will be upgraded to MS 20 Block 2 level. New weapons would be added to the arsenal of the Hungarian Gripens. [211] The IRIS-T missiles have been ordered in December 2021. [212]
