An increasingly important airborne radar application is making radar maps of sufficiently fine resolution that topographic features and objects on the ground can be recognized. In this chapter, the authors discuss how ground map resolution is defined and see what the optimum resolution is for various uses; then, review the approaches taken to providing it.
