Abstract

The basic principle behind all satellite imaging systems is similar an orbiting platform containing imaging equipment gathers data from a specified section of the earth and transmits the data to an earthbound receiving station where it is analyzed Imaging systems can be divided into those that use framing and those that use scanning techniques The former method captures an area as one image using a photographic plate or other recording medium This is the technique used in traditional aerial and space photography The vast majority of spacebased imaging systems now in operation are scanning systems where one or more detectors collect data by sweeping over the target in parallel scan lines Figure 11 shows a schematic of such a system and illustrates some important scanningsystem terminology
