A tornadic debris signature (TDS), often colloquially referred to as a debris ball, [1] is an area of high reflectivity on weather radar caused by debris lofting into the air, usually associated with a tornado. [1] [2] A TDS may also be indicated by dual-polarization radar products, designated as a polarimetric tornado debris signature (PTDS).
In short-term prediction and detection of tornadoes, meteorologists integrate radar data with reports from the field and knowledge of the meteorological environment. Radar analysis is augmented by automated detection systems called algorithms. Meteorologists first look at the atmospheric environment as well as changes thereof, and once storms ...
FuG 350 Naxos Z: The original system, detected H2S radar system on bombers. Unable to distinguish individual bombers nor the 10 GHz H2X Allied bombing radar, but could reliably guide the fighter into the bomber stream. FuG 350 Naxos ZR: Additional aerials added a tail warning system which allowed British night-fighters to be detected.
When the rain starts to fall, people immediately look to the weather radar to see how long it will last. But when severe weather strikes, meteorologists can use this technology to pinpoint the ...
This is a list of World War II electronic warfare equipment and code words and tactics derived directly from the use of electronic equipment.. This list includes many examples of radar, radar jammers, and radar detectors, often used by night fighters; also beam-guidance systems and radio beacons.
Prior to the introduction of the cavity magnetron, radar systems used traditional vacuum tube electronics and were limited to about 1.5 m wavelength in UK use, and as low as 50 cm in German systems. Both could receive the transmissions of their opposing radar systems and radar warning receivers were widely used by both sides in a number of roles.
DFR7. This low-cost detector has impressive range and all the requisite features, including GPS for low-speed false-alert muting, manual marking of up to 100 known radar locations, and speed ...
Radar cross-section (RCS), denoted σ, also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. [1] An object reflects a limited amount of radar energy back to the source. The factors that influence this include: [1] the material with which the target is made;
