摘　　要：提出一种新的基于多特征多分辨率的快速SAR图像匹配算法。算法主要包含图像预处理、匹配特征选择、匹配准则定义、搜索策略设计、匹配结果融合5部分。算法采取在不同图像尺度上分别基于具有信息互补关系的不同特征进行匹配的策略,兼顾了匹配精度与时间效率。实验结果验证了算法的有效性。A novel high-speed synthetic aperture radar（SAR） image matching algorithm is proposed by exploiting muhi-feature and multi-scale strategy is proposed. The framework of this algorithm is com- posed of 5 sub-modules： image pre-processing, matching feature selection, matching rule definition, searching strategy and matching results fusion. The proposed algorithm adopts different and complementary features for matching operations on images under different scales, and gains improvements both in matching accuracy and time efficiency. The experimental results demonstrate the effectiveness of this method
