Abstract
The HRGB method is an alternative to Fourier and back projection techniques for image reconstruction from k-space or I&Q SAR datasets. The method is highly parallelizable, and does not rely on interpolation. The resulting images can thus be computed quickly, with accuracy exceeding back projection techniques. The HRGB method has been shown to be particularly suitable to trapezoidal/keystone SAR grids. The present paper discusses the HRGB method as applied to polar-grid SAR image reconstruction, such as for spotlight SAR and ViSAR. The discussion includes steps for 3D wavefront curvature compensation.
