Abstract :
Normally SAR-mapping is performed along a straight path. A curved path might increase the mapping rate significantly, however. Drawbacks are more complex signal processing and that defocusing may occur. In this paper, curved SAR-mapping is analysed in more detail including forward look geometry. Relationships are shown how resolution performance and mapping rate are influenced by the curved SAR-path. Examples are also presented showing how the phase error depends on side acceleration and scene geometry
