The most widely used active remote sensing systems include: Active microwave (RADAR= RAdio Detection and Ranging), which is based on the transmission of long-
2-Active remote sensing, on the other hand, emits energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation

Remote sensing imagery has many applications in mapping land-use and cover, Remote sensing can be either passive or active ACTIVE systems have their
photography, radiometers, and infrared Active remote sensing Active sensors use internal stimuli to collect data, emitting energy in order to
Radar is an active remote sensing system operating at the microwave The sensor transmits a microwave (radio) signal towards a target and detects the
passive and active remote sensors can collect data twenty-four hours a day in the visible, infrared and microwave regions of the electromagnetic spectrum
