A Hyperparameter-free Total Variation Regularization Method for Real Aperture Radar Angular Super-resolution

A real aperture radar has physical space limitations that result in a wide antenna beam, leading to low angular resolution. The angular super-resolution method based on sparse reconstruction introduces sparse prior constraints of the target under a regularization framework and reconstructs the targe...
