Fast Realization of High Resolution Computational SAR Imagery of Complex Objects

Fast realization of high resolution computational synthetic aperture radar (SAR) imagery of complex object is highly demanded due to its wide applications. To generate computational SAR images with high resolution, this paper presents our recent development on (i) how to develop hybrid HF method to efficiently generate EM scattering database of wide-angel and wideband, and (ii) how to process the obtained EM data to produce high resolution SAR imagery. Simulated example clearly shows that the developed hybrid HF method is capable of generating EM scattering data that can be processed into high resolution SAR images.
