| If the standard RDA (Range-Doppler Algorithm) for the ISAR (Inverse Synthetic Aperture Radar) image formation task is used, the obtained images are usually defocused, specially when large illumination times are processed. Hence, if the CPI (Coherent Processing Interval) is reduced, the blurring is mitigated, but the Doppler (azimuth) resolution is degraded. Nevertheless, superresolution algorithms may be applied in this context to improve the standard Fourier resolution. In this paper, the performance of these superresolution approaches is evaluated. We conclude that the quality of the obtained ISAR images is not enhanced in comparison with the results obtained after applying motion compensation-based techniques. | |
