Calibration and extraction of features for SISAR shadow image
SISAR侧影像的校正及特征提取

Based on an analysis of the principle SISAR shadow imaging, the effect on target shadow image due to nonconstant velocity rotation relative to the target is first examined, and a compensation method is also presented. In addition, the effect on target shadow image due to target motion parameters is described. Eventually, a target recognition approach on the basis of the invariable parameters obtained is proposed. The computer simulations show the efficiency of the method.
