The effect of wave polarization on object texture features in polarimetric SIR/C-X-SAR images is examined through the calculation of surface fractal dimension and Haralick’s second- order statistics. The performed analysis of variances of fractal dimension mean values of natural objects 'forest' and 'water' didn't reveal polarization influence on mean values before speckle filtering, but revealed statistically reliable differences in mean values for some pairs of samples after speckle filtering. The incidental nature of observed differences in mean values of fractal dimension is shown for co- polarization VV-HH and cross –polarization HV-VH pairs of samples. This conclusion is true also for Haralick's textural features 'contrast', ‘inverse moment’ and 'entropy' for the object 'water'. Statistically valid differences by wave polarization are revealed in mean values of Haralick's textural features for objects 'city' and 'water' both until and after speckle filtering. Analysis of variances showed that differences in mean values of textural features for object 'forest' are statistically doubtful at change of polarization. Calculations were made in 28*28 pixels window series sized N=20 for every image object (‘forest’, ‘town’, ‘water’) in four polarizations (HH,VV,HV,VH), two wave lengths (L- and C-) SIR/C-X-SAR images
