滑动聚束模式的RD成像。聚束模式SAR中,天线始终指向场景中心,合成孔径的长度比相同条件下的条带式SAR长。对于滑动聚束模式SAR系统,由于天线的指向变化与两者都不同,所以与条带模式相比,其合成孔径更长,而且测绘带区域比聚束模式更大 (The Sliding Spotlight model described in the article can geta better resolution than strip-map mode and better observed area than spotlight mode.by steering the antenna on a point further away the radar than the area beingilluminated which can be regarded as coming the underground. By doing this, thismode can get good combination between the resolution and observed area. )

最长公共子序列的个人实验，输入两个不同的字符序列（要求必须是字母），将输出这两个字符序列的最长公共子序列。(Individual experiments longest common subsequence, enter two different sequences of characters (letters must be required), the output of the longest common subsequence of the two-character sequence.)

代码主要是针对进一步了解MatLab软件/语言，学会使用MatLab对图像作滤波处理，使学生有机会掌握滤波算法，体会滤波效果。 了解几种不同滤波方式的使用和使用的场合，培养处理实际图像的能力，并为课堂教学提供配套的实践机会。 计算得到的。空域滤波基本上是让图像在频域空间内某个范围的分量受到抑制，同时保证其他分量不变，从而改变输出图像的频率分布，达到增强图像的目的。(Central South University Institute of the fourth channel digital image processing)

Demo for Binary Iterative Hard Thresholding

信号由三个频率分别为0.01，0.1，0.2的正弦信号组成。 (1)作信号的连续小波变换。 (2)自己选择小波基数，对信号进行多尺度分解，将每一个正弦信号分开。 (3)重建原信号。 (Signal from the three frequencies were 0.01,0.1,0.2 sinusoidal signals. (1) continuous wavelet transform for signal. (2) choose the wavelet base, multi-scale decomposition of signals, a sinusoidal signal of each separate. (3) reconstruction of the original signal.)
