N2 - Curved Spaceborne Synthetic Aperture Radar (SAR) 3D imaging has the advantage of high timeliness and is a hot topic in the field of SAR 3D imaging research. However, current studies do not sufficiently analyze the factors affecting curved SAR 3D reconstruction. Therefore, this paper first derives an analytical model for target reconstruction accuracy based on the discrete fractional Fourier transform (FrFT) and verifies the theoretical correctness through simulations. Secondly, simulations demonstrate the impact of FrFT search step size on reconstruction performance, and finally, the correctness of the theoretical model is proved by vertical surface target simulation.
