基于MATLAB GUI的SAR杂波统计建模与仿真系统设计

摘要

The study of SAR clutter statistical characteristics is very important for SAR image interpretation. A SAR clutter statistical modeling and simulation system is designed by using MATLAB GUI tool. The method of designing the graphical user interface and implementation procedure of the software is introduced in detail. And an experiment is carried out on this system by using airborne SAR image. The system with friendly interfaces has easy operation, strong expansibility and perfect function including data preprocessing, clutter statistical analysis, clutter simulation and speckle filtering. It can be used in teaching, scientific research and experimental analysis which are related to SAR.%SAR图像杂波统计特性研究对于SAR图像的解译具有十分重要的意义.利用MATLAB GUI工具设计了SAR杂波统计建模与仿真系统.详细介绍了图形用户界面的制作方法以及软件的设计与实现过程.并利用该系统对机载SAR数据进行了实验.系统具有图像预处理、杂波统计分析、杂波仿真、相干斑抑制等功能,界面友好、操作方便,且具有可扩展性,可用于与SAR有关的教学、科研与实验分析.
