Radar theory

thumb|A wine glass in an [[LCD projector's light beam makes the beam scatter.]] In physics, scattering is a wide range of physical processes where moving particles or radiation of some form, such as light or sound, are forced to deviate from a straight trajectory by localized non-uniformities (including particles and radiation) in the medium through which they pass. In conventional use, this also includes deviation of reflected radiation from the angle predicted by the law of reflection. Reflections of radiation that undergo scattering are often called diffuse reflections and unscattered refle

measure of how detectable an object is by radar

type of radar system used in air traffic control

error in the perception or representation of any visual or aural information

number of pulses of a repeating signal in a specific time unit

unwanted signals, echoes, or images on the face of the display screen, which interfere with the observation of desired signals

type of radar

radar sensor that illuminates a large portion of space with an electromagnetic wave and receives back the reflected waves from targets within that space

radar signal processing technique used to distinguish targets from clutter

distance at which the radar beam rises enough above the Earth's surface to make detection of a target at low level impossible
