Contrastive Domain Adaptation-Based Sparse SAR Target Classification under Few-Shot Cases

Remote Sensing, 2023
Due to the imaging mechanism of synthetic aperture radar (SAR), it is difficult and costly to acquire abundant labeled SAR images. Moreover, a typical matched filtering (MF) based image faces the problems of serious noise, sidelobes, and clutters, which ...
