Abstract

SAR-mapping is usually performed along a straight path. A curved path might increase the mapping rate significantly. Drawbacks are more complex signal processing and that defocusing may occur. In this paper, curved SAR-mapping is analysed in more detail including more forward look geometry. Relationships are derived how SAR-resolution and mapping rate are influenced by the curved SAR-path. Examples show how the non-linear phase error depends on side acceleration and scene geometry.
