中文摘要：

MIMO（Multiple-InputMultiple-Output）雷达是一种新体制雷达，具有潜在的对空中目标实时成像能力。论文首先建立了MIMO雷达观测信号模型，结合等效相位中心近似，以MIMO雷达对空中目标成像为目的提出一种天线布阵方式。基于这种布阵方式，推导出适用于MIMO雷达的修正距离偏移成像算法。最后对布阵方式的合理性和成像算法的有效性进行了成像仿真验证。

英文摘要：

MIMO （Multiple-Input Multiple-Output） radar is a new approach to radar, which has a potential to image airborne moving target. Firstly, this paper establishes a signal model. According to displaced phase center （DPC） approximation, an arrangement of antenna arrays is proposed for MIMO radar imaging of airborne target, and then a modified range migration algorithm for MIMO radar is described. Finally, simulations are performed in order to validate the effectiveness of the imaging algorithm and the array arrangement.
