Reconstruction using CSLP, CSGBP, and iterative CSGBP.
(a) Original scene used for showing effects of range pixel, azimuth pixel, and range velocity mismatch
(b) Reconstruction using CSLP. Points at (7, 65) and (2, 70) are not identified
(c) Reconstruction using CSGBP. All range positions are correctly identified
(d) Reconstruction using iterative CSGBP. Points moving at 3.3 m/s are focussed
(e) Reconstruction using iterative CSGBP. Point moving at −4.9 m/s is focussed
(f) Reconstruction using iterative CSGBP. All points are focussed
