It is much easier to spot patterns in your data when you can associate an image with each datapoint. thumbnailScatter.m overlays an image thumbnail over each datapoint to help with visualization. For example, if you perform a principal components analysis and would like to plot PC1 vs PC2, use thumbnailScatter.m to see what properties each PC controls. Run demo_scatterThumbnail.m to see how it works. Test data are provided for the demo.

Image Compression A collection of simple routines for image compression using different techniques. BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function conv2fft performs a 2D FFT-based convolution. Type help conv2fft on MATLAB command window for more informations.

1.本程序是自己刚刚接触SAR时编写的时域星载SAR点目标回波仿真，包含了卫星轨道模型、计算星目斜距时用到的各种坐标系转换、SAR回波计算模型以及简单的SAR成像模型，希望对初学者有所帮助。 2.相应的参考资料可查找《卫星轨道姿态动力学与控制》及《魏钟铨_合成孔径雷达卫星》；(1. This program is just contact with their own prepared when the time domain SAR spaceborne SAR point target echo simulation, contains the satellite orbit model, the satellite project when the use of a variety of slant range coordinate system conversion, SAR echo calculation model and SAR imaging model simple, want to help beginners. 2. The corresponding reference can be to find " satellite attitude and orbit dynamics and control" and " Wei Zhong Quan _ synthetic aperture radar satellites" )
