Radar is electromagnetic sensing used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distances.
It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them.
The targets may be aircraft, ships, spacecraft, automotive vehicles, and astronomical bodies – even birds, insects, and rain. Besides determining the presence, location, and velocity of such objects, radar can sometimes obtain their size and shape as well.
What distinguishes radar from optical and infrared sensing devices is its ability to detect faraway objects under adverse weather conditions and to determine their range, or distance, with precision.
Developed around the time of World War II, there is still a primary association of radar with the Department of Defense and military applications. However, over the past 50 years, weather radar has risen to prominence. Of particular importance has been its ability to detect and warn of hazards associated with severe local storms that include hail, tornadoes, high winds and intense precipitation.
Weather radar also monitors larger weather systems such as hurricanes that often include similar phenomena but can extend over very large areas. Weather radars improve aviation safety and increase the operational efficiency of the entire air transport industry, and they contribute to agriculture alerts and flood warnings through monitoring of rainfall intensity.
Weather radar is also used regularly for recreational planning and other weather-impacted activities.
Radar measurements have also been key to many remarkable advances in understanding the atmosphere and better weather prediction over a variety of temporal and spatial scales. Such advances have been enabled through a combination of progressive improvements in radar hardware, signal processing, automated weather-based algorithms and displays.
