Although radar uses electromagnetic waves outside of the visible spectrum (radio waves) instead of light, it still relies on the same wave-reflect-capture process. Radio waves travel at the same speed as light but have the lowest frequency of the spectrum (meaning they have the longest wavelength).

Radar can decipher how far away precipitation is, its speed and how big droplets or snowflakes are. This data can then be used in computer forecasting models to predict future weather trends, while alerting meteorologists to upcoming precipitation, storms or severe weather.

At the same time, radar has found an increasing number of important civilian applications, notably air traffic control, weather observation, remote sensing of the environment, aircraft and ship navigation, speed measurement for industrial applications and for law enforcement, space surveillance, and planetary ...

“Radar” is an acronym that stands for “RAdio Detection And Ranging.” A radar is an active sensor that transmits microwave radio signals and receives and processes the backscattered radiation to detect the “targets” that produced it and to quantify the parameters of these backscattered signals.

Radar is used in fighter aircraft for finding enemy aircraft and controlling air-to-air missiles, rockets, and guns. It is used in bombers to find surface targets, fixed or moving, and to navigate and avoid obstacles.

The full form of RADAR is Radio Detection And Ranging.

RADAR is helpful in detecting incoming signals during war and also used by a geologist for earthquake detection. Archaeologists use this technology for detection of buried artifacts. It is also used to understand the environment and climatic changes.
