DOI: 10.1109/tgrs.2022.3204077
Abstract: Inverse synthetic aperture ladar (ISAL) can perform high-resolution imaging for satellites. However, due to the short wavelength of the laser, satellite microvibration will introduce space-variant vibration phase error (SVVPE) and space-invariant vibration phase error (SIVVPE)… read more here.
