When the conventional methods of sidelobe suppression are used in multiple input multiple output synthetic aperture radar( MIMO-SAR) systems to generate images for diagnosing the near field scattering features of targets,non-orthogonal sidelobes can hardly be suppressed efficiently. In this paper,based on the generation mechanisms of the non-orthogonal sidelobes in near filed,an approach which combines spatially variant apodization( SVA) with tri-apodization was proposed to suppress the non-orthogonal sidel...
