The technique of SLAR imaging and the various aerial and space-borne SLAR sensors were discussed in the preceding chapter. Briefly, the radar mounted on the base of the sensor platform looks sideways down on the Earth, transverse to the flight direction. It emits pulses of microwave energy, which illuminate long narrow stripes on the ground. The back-scattered signal, sensed by the antenna, is recorded in order of arrival time. This yields a radar image.
