A lightning detector is a device that detects lightning produced by thunderstorms. There are three primary types of detectors: ground-based systems using multiple antennas, mobile systems using a direction and a sense antenna in the same location (often aboard an aircraft), and space-based systems.
A Perry Weather lightning warning system. The detection equipment is designed to constantly survey atmospheric electrical activity and potential for lightning occurrence via radar and other methods. [citation needed] Storms are scanned by radar to determine the degree of electrification and potential for lightning occurrence. [citation needed]
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.
Most of today's radar detectors detect signals across a variety of wavelength bands: usually X, K, and K a. In Europe the K u band is common as well. The past success of radar detectors was based on the fact that radio-wave beams can not be narrow-enough, so the detector usually senses stray and scattered radiation, giving the driver time to ...
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 ...
The Blighter B202 Mk 2 radar from Blighter Surveillance Systems (a Plextek Group company) is an advanced E-Scan radar with no moving parts for high reliability in the field. Its weight is about 15 kg and is therefore truly man portable, about the weight of a machine gun and less than half the weight of other man-portable radars.
Millimeter wave (mmWave) sensing is a non-contact system of using mmWave radar sensors to measure movement, acceleration, and angles as small as a fraction of a millimeter. [1] This system requires a mmWave radar sensor to transmit and receive pulses of millimeter electromagnetic wave energy, detecting targets and motion from the reflections it ...
Motorway Incident Detection and Automatic Signalling, usually abbreviated to MIDAS, is a UK distributed network of traffic sensors, mainly inductive loops (trialling at the moment radar technology by Wavetronix and magneto-resistive wireless sensors by Clearview Intelligence), which are designed to alert the local regional control centre (RCC) to traffic flow and average speeds, and set ...
