The technique of SLAR imaging has been 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 strips on the ground. The back-scattered signal, sensed by the antenna, is recorded in order of arrival time. This yields a radar image.
