Abstract
In Inverse Synthetic Aperture Radar (ISAR) imaging, with the increase of range and cross-range resolutions, scat-terers move through resolution (range and cross-range) cells even in short coherent processing interval. This limits the resolution obtained and degrades the image quality for the conventional Range-Doppler method. In this paper, the Migration Through Range Resolution Cell (MTRRC) is mitigated by forming the cross-range image for every frequency, while the Migration Through Cross-range Resolution Cell (MTCRC) is mitigated by using dechirp processing.
