Inverse synthetic aperture ladar imaging algorithm for space spinning targets
The Journal of Engineering, 2019 Due to the limitation of laser modulation technology, the azimuth Doppler ambiguity problem exists in the process of inverse synthetic aperture ladar (ISAL) imaging for spinning targets. The traditional azimuth imaging method will not be used to obtain a
