In the last chapter, we saw how SAR takes advantage of a radar's forward motion to synthesize a very long linear array from the returns received over a period of up to several seconds by a small real antenna. We learned how the array may be focused at virtually any desired range and how the immense amount of computing required for digital signal processing may be dramatically reduced through doppler filtering techniques. In this chapter, we will consider certain critical aspects of SAR design which, if not properly attended to, may seriously degrade the quality of the maps or perhaps even render them useless: selection of the optimum PRF, sidelobe reduction, compensation for phase errors resulting from deviation of the radar bearing aircraft from a perfectly straight constant - speed course - called motion compensation - and the minimization of other phase errors.
