This paper analyses the sparsity of SAR signal under the multi-antenna observation structure. Based on the sparsity of continuous scene spectrum and sparsity of target scene, a down-sampling method is proposed and side-looking 3D imaging of cross-track sparse array SAR is investigated. Imaging results on simulation and real data are given to verify the proposed method.
