A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
KTAB-TV (channel 32) is a television station in Abilene, Texas, United States, affiliated with CBS and Telemundo. It is owned by Nexstar Media Group , which provides certain services to NBC affiliate KRBC-TV (channel 9) under joint sales and shared services agreements (JSA/SSA) with Mission Broadcasting .
Once the radar can "look down", it is subsequently desirable to "shoot down". Various weapons systems (including guns and missiles) are then employed against designated radar targets, either relying on the aircraft's radar employing the "look down" capability (as in semi-active radar homing) or the weapon's own active radar to resolve the indicated target (as in active radar homing).
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
Antenna motion for pulse-Doppler must be as slow as radar using MTI. Search radar that include pulse-Doppler are usually dual mode because best overall performance is achieved when pulse-Doppler is used for areas with high false alarm rates (horizon or below and weather), while conventional radar will scan faster in free-space where false alarm ...
The Rapid X-band Polarimetric Radar, commonly abbreviated as RaXPol, [1] is a mobile research radar designed and operated by the University of Oklahoma, led by Howard Bluestein. RaXPol often collaborates with adjacent mobile radar projects, such as Doppler on Wheels and SMART-R . [ 2 ]
The drawback is that once the radar is set to tracking a single target, the operator loses information about any other targets. This is the problem that track while scan is meant to address. In traditional radar systems, the display is purely electrical; signals from the radar dish are amplified and sent directly to an oscilloscope for display ...
The Erieye AEW&C mission system radar is an active, phased-array, pulse-doppler sensor that can feed an onboard operator architecture or downlink data, via an associated datalink subsystem, to a ground-based air defence network. The system employs a large aperture, dual-sided antenna array housed in a dorsal 'plank' fairing.
