FPGA Implementation of a SAR Two-dimensional Autofocus Approach

FPGA Implementation of a SAR Two-dimensional Autofocus Approach

For real-time autofocus of defocused images produced by Synthetic Aperture Radar (SAR), the twodimensional autofocus approach proposed in this study is used to correct the residual range cell migration and compensate for the phase error. Next, a block-wise Phase Gradient Autofocus (PGA) is used to c...
