本义研究合成孔径雷达（ＳＡＲ）图象结构特征检测。首先讨论了 ＳＡＲ图象结构检测的原理，然后在分析Ｌｏｐｅｓ等人的算法的基础上，提出了一个改进的结构检测算法，给出改进算法的实现流程，并利用模拟和实测ＳＡＲ图象进行试验比较，充分验证了改进方法的优越性和实用性。
The original meaning of Synthetic Aperture Radar (SAR) image structure feature detection. Firstly, the principle of SAR image structure detection is discussed. Then an improved structure detection algorithm is proposed based on the analysis of Lopes et al. Algorithm. The implementation process of the improved algorithm is given. Experiments with simulated and measured SAR images Comparison, fully validated the superiority and practicality of the improved method.
