摘　　要：本文针对多源SAR遥感影像联合定位的实际问题,将有理函数模型引入到SAR影像联合定位中,构建了基于有理函数模型的多源SAR区域网平差模型。对覆盖我国某地区的3景不同源SAR影像进行试验,验证了本文方法的有效性,并表明在缺少地面控制情况下,该方法不失为一种有益的补充方案。For the combined location problem of multi-sensor SAR remote sensing imagery, the Rational Function model was in- troduced in this paper, and the RFM-based block adjustment method was constructed. Through the experiment of three scenes multisensor SAR imagery covering some places in China, it verified the effectiveness of the method, and in the case of absence of ground control points, the method may well be a useful complement to the solution.
