使用距离徙动算法解决SAR的成像问题，采用插值运算(Using range migration algorithm to solve the imaging problem of SAR,Interpolation operation)

Several new methods sar image denoising, It draws on principal component analysis algorithm (PCA), Least-squares algorithm to fit a three-dimensional plane.

This is a useful frequency estimation algorithm matlab simulation program, Data analysis, plotting, etc., Synthetic Aperture Radar (SAR) imaging simulation target.
