Spotlight mode Synthetic Aperture Radar (SSAR) has the capability to offer very high image geometric resolution in the azimuth direction. This is attributable to the continuous steering of the airborne or spaceborne antenna so that the transmitted beam remains focused on the target scene of interest thereby increasing the radar viewing angle. Further improvement of azimuth resolution is achieved by narrowing the transmitted beam. The range resolution on the other hand, significantly depends on the duration of the transmitted linear frequency modulated (LFM) pulse. The longer the pulse duration the wider the bandwidth and the better image range resolution ...
