Explain the qualitative difference between SAR and optical imagery at low grazingangles and at high grazing angles.2. Where is the radar in any given image? What clues can you use to decide?3. What is the relationship between range resolution in the slant plane and the groundplane? What about cross-range resolution?4. Derive the angular and along-track sampling requirements, δφ and δx, for a collectionwhere the radar is squinted by θ sq relative to broadside in the ground plane (orequivalently by θ cone relative to the velocity vector).5. Use a computer programming language to write a truncated sinc interpolator. Use thesoftware to reproduce the results shown in Figure 6-16.6. Describe the major sources of noise in SAR imagery. Explain the difference betweenadditive and multiplicative noise. To which category does receiver phase noise belong?What about rainfall within the scene?7. Azimuth ambiguities are usually treated as uncorrelated noise when predicting imagequality. However, very bright features such a buildings, towers, and bridges can appearappear in a SAR image as azimuth ambiguities. Will these ambiguous features beproperly focused by the polar format algorithm?
258 CHAPTER 6 Spotlight Synthetic Aperture Radar8. The transmitted bandwidth of a radar is often idealized as having a constant valueacross the band. What happens to the range profile if the spectrum amplitude exhibitsa sinusoidal variation (often called passband ripple)? Is the cross-range character ofthe image affected?9. Figures 6-11 and 6-12 depict the fact that spotlight SAR imagery is usually formedby retaining the largest rectangular region that can be inscribed in the annular spectralsupport of the radar data. Write the expressions for the dimensions of this rectangle.10. Assuming the cross-range resolution is fixed, does increasing the radar’s center frequencyreduce or increase the effect of quadratic phase error?
