摘　　要：无论是供机上操作人员实时地观察还是将数据下传到地面接收站,综合孔径雷达成像系统都必须具有实时成像处理的功能,而且要求能够实时地输出大面积的连续图像.以SPECAN法为基础,提出一种可以实时输出大面积连续图像的综合孔径雷达成像方法,该方法具有运算量小、编程方便和稳健性高的特点,可满足综合孔径雷达实时处理机的要求.A unmanned aerial vehicles (UAVs) SAR imaging system must produce continuous SAR images in real-time, which requires the imaging algorithms to possess a less computing load, simple realization and robustness. An algorithm is given in this paper which is based on the SPECAN algorithm and can satisfy all the requirements mentioned above.
