Abstract

In spaceborne synthetic aperture radars (SARs), the orbit curvature may prevent the use of the processor, causing artifacts that depend on both the extent of the orbit arc and the slant range interval. A viable solution has been derived by extending the singular value decomposition-Stolt approach that was proposed for geophysical applications to microwave SAR. The resulting processor has the same simple scheme as the approach but a different (numerical) computation of both the reference and the Stolt interpolation.
