Radar is a system that uses radio waves to determine the distance (ranging), 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.

Follow along with us on the latest weather we're watching, the threats it may bring and check out the extended forecast each day to be prepared. You can find the forecast for the days ahead in the...

2025年3月21日 · Radar, electromagnetic sensor used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distance. It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them.

Weather Underground’s WunderMap provides interactive weather and radar Maps for weather conditions for locations worldwide.

Radar Functions • Normal radar functions: 1. range (from pulse delay) 2. velocity (from Doppler frequency shift) 3. angular direction (from antenna pointing) • Signature analysis and inverse scattering: 4. target size (from magnitude of return) 5. target shape and components (return as a function of direction) 6. moving parts (modulation of ...

2023年9月27日 · The word radar comes from the acronym radio detection and ranging. As the name implies, radars use radio waves to determine the distance and velocity of the targets they hit. A radar system usually consists of a transmitter to send out radio signals and a receiver to catch any reflected energy from targets.

Radars are critical for understanding the weather; they allow us to “see” inside clouds and help us to observe what is really happening. Working together, engineers, technicians, and scientists collectively design, develop and operate the advanced technology of radars that are used to study the atmosphere. What are Weather Radars?

Modern weather radars are mostly doppler radars, capable of detecting the motion of rain droplets in addition to intensity of the precipitation. Both types of data can be analyzed to determine the...
