摘要
According to an embodiment of the present invention, when generating a SAR image to which FBPA is applied in an environment in which there is a distance due to a nonlinear flight trajectory and an altitude direction deviation, a local polar coordinate on a slope plane for each partial aperture is a distance direction of each slope plane, an aircraft flight It is possible to generate accurate SAR image for the target by applying BPA by converting the normal direction of the direction and inclined plane to the local Cartesian coordinate system.
