DOI: 10.1109/lawp.2018.2829826
Abstract: Synthetic aperture radar automatic target recognition (SAR ATR) is a powerful tool for recognizing targets. The SAR ATR needs a massive database of inverse synthetic aperture radar (ISAR) images from computer-aided design (CAD) models for… read more here.

DOI: 10.1109/lgrs.2022.3210036
Abstract: Inverse synthetic aperture radar (ISAR) is an effective detection method for targets. However, for the maneuvering targets, the Doppler frequency induced by an arbitrary scatterer on the target is time-varying, which will cause defocus on… read more here.

DOI: 10.1109/taes.2018.2814211
Abstract: In this study, we propose an efficient strategy to exploit cross-range resolutions (CRRs) of inverse synthetic aperture radar (ISAR) images to improve classification performance. The proposed method preprocesses an ISAR image of an unknown target… read more here.
