Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
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.

What they look like: With over 200 species of wolf spiders crawling around, it’s no wonder that they range in size and appearance. “The largest species can be up to an inch and a half long ...
The Doppler image to the right shows an example wherein a group of bats is overtaken by a thunderstorm. [15] In the image, the bats are in the red zone, which corresponds to winds moving away from the radar station, and enter into a mesocyclone associated with a tornado (in green). These events may occur easily with birds, which can get killed ...
[67] [68] The flexibility of their silk draglines can aid the aerodynamics of their flight, causing the spiders to drift an unpredictable and sometimes long distance. [69] Even atmospheric samples collected from balloons at 5 km (3.1 mi) altitude and ships mid-ocean have reported spider landings. Mortality is high. [70]
