Flight path-driven mitigation of wavefront curvature effects in SAR images

Patent ·
OSTI ID:982373

A wavefront curvature effect associated with a complex image produced by a synthetic aperture radar (SAR) can be mitigated based on which of a plurality of possible flight paths is taken by the SAR when capturing the image. The mitigation can be performed differently for different ones of the flight paths.
