PhySR: Physics-Informed Neural Network for Super-Resolution Reconstruction in Radio Synthesis Imaging
PhySR is an end-to-end physics-informed neural network that combines a U-Net backbone, dynamic cascaded upsampling, a multiscale feature residual module, and a differentiable physical forward model incorporating the primary beam response, PSF convolution, and scale mapping that directly reconstructs high-resolution ima...
