  • Due to the high system Degrees of freedom (DOF) by utilizing the multiple transmitting elements and receiving elements, MIMO-SAR can improve the performance of static scene imaging and Ground moving target indication (GMTI), simultaneously. To realize the above multifunctional design, the optimal linear array configuration is given for MIMO-SAR in this paper at first. Furthermore, the DOF tradeoff schemes are proposed for static scene imaging and GMTI. Meanwhile, it is shown that the tradeoff between azimuth high-resolution and wide-swath can be solved by MIMO-SAR more effectively than the existing Multiple phase centers SAR (MPC-SAR). The proposed four propositions and numerical experimental results are provided to demonstrate the effectiveness of MIMOSAR.
