Application of 2-D RELAX algorithm to SAR superresolution imaging

Design and develop a set of microwave imaging system based on synthetic aperture radar (SAR)technique. Superresolution array processing methods have been applied to SAR imaging in order to improve the resolution. The application of the 2-D RELAX algorithm in SAR imaging is introduced in this paper. Therefore, the higher resolution can be obtained by using the RELAX algorithm instead of the FFT. The experimental results show the effectiveness of RELAX algorithm.
