Imaging algorithm study on ARC antenna array ground-based SAR

Ground-based SAR has become an important remote sensing technology means for deformation monitoring in recent years. However, in order to achieve higher efficiency data acquisition and wider observation, arc antenna array technology is applied to ground-based SAR. In this paper, a polar format imaging algorithm for arc antenna array ground-based SAR is proposed. Firstly, a brief background on ground-based SAR and arc antenna array are provided. Then, the signal model and imaging algorithm of arc antenna array ground based-SAR are introduced. Finally, simulation result is presented.
