研究了乘积模型和相应的K分布对高分辨率图像的有效性。特别感兴趣的是几种类型的杂波的序参量及其与极化的关系。在实验测试中，大多数杂波的低阶参数被测量到，表明高分辨率增强了纹理效果。此外，扩展的产品模型，考虑从多个层的后向散射，为了解释极化的变化，在L波段的森林地区的测量顺序参数。
The validity of the product model and the corresponding K distribution for high resolution images is studied. Of particular interest are the order parameter for several types of clutter and its relation to the polarization. In experimental tests, low order parameters are measured for most clutter, indicating the high resolution enhances the texture effect. Also an extension of the product model considering backscattering from multiple layers is presented, in order to explain polarimetric variation in the measured order parameters for the forest areas at L-band.
