Research on Statistical Analysis of SAR Images
The statistic distribution of SAR image plays an important role in SAR image processing,and it has a great influence on the results.In practical applications,the distribution is often specified by human through experience,but in fact the distribution changes with different pictures of different scenes.In this paper we first find a way to determine the form of the image distribution with Pearson system,and then we use the Chebyshev-Hermite polynomials and the statistical properties of SAR image to get the Edgeworth expansion.Finally,we practice the distribution simulation on four different types of scene (the ocean,the town,the mountain and the agricultural fields). The experimental results prove the efficiency and the accuracy of these two methods,and will lay a good foundation for the follow-up steps in image processing.
