Radar imagery

This tutorial paper disusses radar imagery from several viewpoints. Various processing tasks of radar data and imagery data are briefly discussed. Some of the main properties of radar images are pointed out and the differences between optical and radar imagery are discussed. The problem of image quality is reviewed with reference to works in optical and radar imagery. Computer processing of radar imagery is considered and various tasks like image encoding and enhancement, rectification and feature processing are briefly commented on, using examples from radar. Finally, computer analysis of imagery in general and radar imagery in particular is discussed and the limitation of pattern recognition methodology for image analysis is pointed out.
