WebRadar —An active radio detection and ranging sensor that provides its own source of electromagnetic energy. An active radar sensor, whether airborne or spaceborne, emits microwave radiation in a series of pulses from an antenna. When the energy reaches the target, some of the energy is reflected back toward the sensor. Web18 Dec 2013 · An active sensor (above left) is a radar instrument used to measure signals transmitted by the sensor that were reflected, refracted or scattered by Earth's surface or atmosphere. A passive sensor (above right) is a microwave instrument designed to receive and measure natural emissions produced by constituents of Earth's surface and …
