本文尝试应用基于POLSAR图像分析的混合分类技术对新潟县中部地震灾区的人工住宅进行检测。该混合方案包括基于物理散射性质的散射功率分解方法和基于极化相关系数的散射特征提取方法。通过对实际POLSAR数据的图像分析，验证了该混合方案即使在恶劣山区也能对人造目标进行准确的分类
This report attempts to apply a hybrid classification technique based on POLSAR image analysis to detect the man- made residential houses in a local mountainous area stricken by the Mid Niigata Prefecture Earthquake. The present hybrid scheme includes the scattered power decomposition method based on physical scattering nature and the scattering feature extraction method using polarimetric correlation coefficient. From the results of the image analysis for actual POLSAR data, it is verified that the present hybrid scheme provides us accurate classification of the man-made targets even in the severe mountainous
