Abstract

To date the main cartographic use of spaceborne remote sensing techniques has been through the application of passively sensed data from instruments such as cameras and scanners. In the next few years considerable actively sensed satellite radar coverage of Australia is planned. These satellite systems are to be flexible in terms of varying look angle, differing emitted frequencies and multipolarization. This flexibility should allow acquisition of pseudo multispectral data and improve the information content for cartographic applications. The maximizing of potential benefits from this expected wealth of remotely sensed data will require users to apply the specialized techniques necessary for handling actively sensed imagery. This paper is not a definitive work on radar. Rather, it seeks to stimulate awareness of radar remote sensing by providing an overview of radar systems and the process of data acquisition and imagery formation. The interpretation of radar imagery is also discussed and the variability of the topographic content of radar data is demonstrated.
