Research of InISAR imaging based on joint translational compensation
The Journal of Engineering, 2019 In order to solve the problem that conventional inverse synthetic aperture radar three-dimensional (InISAR 3D) imaging methods need too much computation and so many restrictions in image registration step, this study proposes an InISAR 3D imaging ...

Long-Time Observation-Based Multiattitude ISAR Imaging Method for Moving Ships
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingLong-time synthetic aperture radar observation facilitates the tracking and identification of moving targets. However, continuous changes in the attitude of a moving target during long-duration observations cause the azimuth signal’s time– ...
