1. Radar monitoring is studying the current weather radar. A network of radars makes it possible to study precipitation,
storm development and storm propagation across large areas. Radar monitoring is especially effective over land
where radar systems overlap with each other.
Radar is a detection system that uses radio waves to determine the distance (ranging), angle, and radial velocity of
objects relative to the site.
ULTRASONIC RADAR is an object-detection system which uses radio waves to determine the range, altitude,
direction, or speed of objects. Ultrasonic Radar systems are used for air-traffic control at airports, and long range
surveillance and early-warning systems. A radar system is the heart of a missile guidance system.
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
