An Improved Parametric Translational Motion Compensation Algorithm for Targets With Complex Motion Under Low Signal-to-Noise Ratios

IEEE Transactions on Geoscience and Remote Sensing, 2022
Translational motion compensation plays an important role in inverse synthetic aperture radar (ISAR) imaging. However, existing translational motion compensation algorithms cannot work well when the signal-to-noise ratio (SNR) is low and the target has ...
