For the real-time transient localization, there are large uncertainties of the fast radio burst (FRB) positions due to the undersampled focal plane in cluster-fed telescopes. A novel focal-field feature matching algorithm based on a conditional generative adversarial network, F3M-cGAN, is proposed for FRB localization. By exploiting the multiple frequency characteristics of FRBs, an improved three-dimensional convolution autoencoder is developed to jointly synthesize focal–field distribution (FFD) features. Meanwhile, the received signals are input as a condition to the discriminator to strengthen the mapping relation. Moreover, an estimator based on a deep neural network is introduced to estimate the position of the FRBs, and a position encoder is designed to enhance the position precision according to the energy distribution. For pattern reconstruction, texture loss is used as feedback for the generator. Based on the alternate training process of the F3M-cGAN framework, effective reconstruction and position estimation could be achieved. A scale model of the Five-hundred-meter Aperture Spherical radio Telescope is used to verify the effectiveness of the proposed method. The simulation results demonstrate that this approach can accurately reconstruct FFD features with limited feeds, and realize a higher real-time localizing precision than the angular resolution of a radio telescope. Furthermore, the proposed method can increase the search area for transients.
