摘要
传统的过合成孔径雷达（ＩＳＡＲ）的成像方法是基于目标作匀速旋转，但是机动性强的非合作目标，非匀速旋转的情况也时有发生，这时会使成像质量下降．本文用等加速旋转模型代替传统的匀速旋转模型，使成像质量得到改善．
Traditional ISAR imaging is based on the uniform rotation of targets. The nonuniform rotation may occur to manoeuvring targets,which will produce smeared images. In this papera constant acceleratively rotating model is used instead of the traditional uniform rotating model.The imaging quality is improved by using the new method.
