KD-ISAR: A Complex-Domain Multilevel Knowledge Distillation Framework for Robust Sparse-Aperture ISAR Imaging
Sparse-aperture inverse synthetic aperture radar (ISAR) imaging suffers from severe underdetermined reconstruction under low sampling rates and residual phase errors, which is further aggravated by insufficient priors of lightweight networks for edge deployment. This letter proposes knowledge distillation (KD)-ISAR, a...
