利用二维有限差分法对单脊波导TM模进行计算。通过调整网格数目观察计算结果的精度，可以设定出最优的网格数目，然后改变波导中脊的尺寸，观察最低两个TM模对应的截止频率的变化规律，最后给出对应的横截面电场、磁场分布图(The two-dimensional finite difference method to calculate the single-ridge waveguide TM mode. The optimal number of grid can be set by the accuracy of the adjustment of the calculation result of the grid number observed, and then change the size of the waveguide ridge observed the lowest two corresponding to the TM mode of the cutoff frequency of the variation, and finally to give the corresponding cross cross-section of the electric field, magnetic field maps)

这是国外人写的一本逆合成孔径雷达雷达（ISAR）成像的基础书，文中每章后带Matalb编写的源代码，对于学习新手非常有用。 (It is written by a foreign foundation book inverse synthetic aperture radar radar (ISAR) imaging, the text written in the source code with Matalb after each chapter, very useful for beginners to learn.)

张正友的Easycalib的程序没有提供源代码，这是matlab实现代码，大家试试！(Easycalib Friends of the procedures did not provide the source code, which is to achieve Matlab code, we try!)
