Radio detection and ranging, an object detection system using radio waves

See the Radar article for a general history of radar

Subcategories

• Doppler radar - a radar that makes use of the Doppler effect to measure velocity at a distance
• Ground penetrating radar - or GPR, a geophysical method that uses radar pulses to image the subsurface of the Earth
• Laser radar - also called "LADAR," for Light Detection And Ranging, a system that uses light or lasers to measure the distance to an object
• Meteorological radar - radar used to detect climatological phenomena
• Millimeter wave radar - or Extremely High Frequency radar, for radar that uses electromagnetic waves in the highest radio frequency band (from 30 to 300 GHz
• Passive radar - radars that detect objects by processing reflections from non-cooperating sources of illumination available in the wider environment
• Radar applications - potential uses of radar
• Radar clutter - unwanted echoes and returns in a radar system
• Radar cross section - or RCS, a measure of how detectable an object is by radar
• Radar equipment - equipment to emit, receive, or measure radar waves
• Radar theory - the theory of the operation of radar waves in the environment
• Spaceborne radar - radar where the transceiver is located in space
• Spread spectrum radar - where a radar signal generated in particular frequency band is spread to cover a wide bandwidth
• Synthetic aperture radar
• Ultra wideband radar - or OWB radar, technology that can be used at very low energy levels for short-range communication, high-bandwidth communication by using a large proportion of the radio spectrum
