The refinement of radar continued until the present and still continues. Today radar is put to use for a multitude of applications, although defense is still one of it's the primary uses. Planes, ships and even some automobiles are guided through a complex and crowed series of thoroughfares with the help of radar. Ultra sensitive radar images transmitted via satellites has shown features of the Earth's topography, such as buried craters and deeply buried faults, that are indiscernible to the unaided eye. Weather forecasting, especially the occurrence and track of severe storms has become much more reliable because of data collected with radar.
Radar is used by the police to catch speeding cars, thereby keeping the roadways safer.
Radar is even used in some common applications, from electric eye doors to speed sensing baseballs to tracking devices given to hikers and skiers. The many functions of radar has changed the way the we both see the world, and travel around it. It has enabled us to travel both further and safer. It has reduced, and in some cases eradicated what would have been limiting conditions of travel in the past. Radar has enabled us to view the world from space, and see what is buried much deeper underground then we could ever reach with a shovel.
