摘要:With the development of spaceborne synthetic aperture radar (SAR), the high resolution has become a hot topic again in recent years. However, the higher the resolution is, the worse the accuracy of the traditional hyperbolic range model (HRM) gets. In the case of ultra-high resolution spaceborne SAR, the curved orbit should be taken into account. To overcome this problem, we present a modified data focusing scheme integrated with state-of-the-art airborne SAR motion compensation methods for spaceborne spotlight SAR. Firstly, one-step motion compensation is selected to correct the orbit curvature effectively, which has been applied in ultra-high resolution airborne SAR systems. Meanwhile, the two-step approach (TSA) is introduced to solve the azimuth spectral folding phenomenon. The simulation results validate the effectiveness of the scheme.
