A tower is a tall Nonbuilding structure, structure, taller than it is wide, often by a significant factor. Towers are distinguished from guyed mast, masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting ...

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 used to detect and track ...

In addition, radar towers are used for the installation and operation of search and height finder radars at military radar stations, where the mission is to support air defense missions. These missions were characterized as Aircraft Control & Warning (AC&W), or Long Range Surveillance in support of the

A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or p ...

A radome (a portmanteau of "radar" and "dome") is a structural, weatherproof enclosure that protects a radar antenna (radio), antenna. The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weathe ...

The data from these radars is fed into the civilian ''RADNET'' system and transferred to all civil and military control centres.
Ideally, a radar tower is built on a high spot in the terrain, because this reduces the
angle of elevation, and thus increases the range of the
radar device. In the absence of a suitable high spot, radar towers are used. Radar towers are also need to provide weather protection and services (air conditioning and power) for the radar equipment, communications, operators and maintainers.

The largest network of military radar stations evolved during the Cold War era to support the air defense of North America as part of the joint US and Canadian command known as the North American Air Defense Command (NORAD). This military radar network became automated in 1960 with the operation of SAGE. SAGE provided the vital command, control, communications, and computers (C4S).
Long Range Radar (LRR) stations were electronically connected to SAGE Direction Centers (DCs). This resulted in an integrated air defense system made up of radar, radio, interceptor aircraft,
antiaircraft guns and missiles, and command and control (C2) facilities. Most of the radar and radio facilities were not on a military air base, but smaller Air Force Stations (AFS), are usually located in rural, and sometimes isolated locations that are often miles away from even small towns. They were staffed by up to several hundred

This includes the
AN/FPS-24 search radar tower that sits in a huge 64 foot square, 85 foot tall, six-story building. On top of this radar tower was a
radar antenna 50 feet tall, 120 feet wide, weighing 85.5 tons, and rotating at 5 rpm. An available rigid radome 140 feet in diameter and 96 feet high protected this antenna from adverse weather conditions.
