PhDGAN: A Physics-Informed Dual-Branch GAN With Gamma-Prior for Dual-Polarization SAR Image Colorization
Synthetic aperture radar (SAR) has become an indispensable tool in Earth observation due to its capability for all-weather and day-and-night data acquisition. However, unlike optical sensors, the inherent coherent imaging mechanism of SAR results in single-channel grayscale images lacking intuitive spectral information...
