Method for Choosing Regularization Parameter in 2D SAR Imaging

For sparse Radar signals, sparse imaging method is subversion of the traditional imaging method, which breaks through the limitations existing in traditional imaging method. In order to improve the imaging quality of Radar signals, we don't only realize the sparse radar imaging algorithm, but also propose a new method for choosing regularization parameter in 2D radar imaging. The imaging result verifies the validity of the new method.
