Sparse Aperture High-Resolution RID ISAR Imaging of Maneuvering Target Based on Parametric Efficient Sparse Bayesian Learning

IEEE Geoscience and Remote Sensing Letters
Inverse synthetic aperture radar (ISAR) imaging for maneuvering targets (MTs) in sparse aperture (SA) conditions is a challenging problem. Range instantaneous Doppler (RID) is useful for ISAR imaging of MT through time-frequency analysis (TFA).
