研究生阶段用的信号处理，这是课后答案，希望能对您有所帮助(Graduate with the signal processing, this is the answer after school, hoping to help you)

说明：  作为具有高分辨以及成像功能的合成孔径雷达，已广泛被各国所研究。而RD算法却是成像领域最基础最最熟的基础算法。在此提供各大家，共同研究！(As well as a high-resolution synthetic aperture radar imaging, has been widely studied by various countries. The RD algorithm is most familiar image of the most basic of basic algorithms. Here are the people, to study!)

稀疏快速傅里叶变换，是一种利用信号频域稀疏特性，只需通过信号部分采样点就可高概率恢复信号频谱的快速傅里叶变换算法。(Sparse Fast Fourier Transformation ，SFFT)

拉哥朗日插值算法的实现,MATLAB编写,仅供参考.(interpolation algorithm implementation, MATLAB prepared for informational purposes only.)

基于MATLAB的共轭梯度BP算法在函数逼近中的实例(MATLAB-based conjugate gradient BP algorithm in the example of function approximation)

给出了用消元法解线性方程组的方法，消元法是解线性方程组有效地方法。(In this paper, the elimination method of solving linear equations, elimination method is effective method of solving linear equations.)

实现希尔伯特-黄变换的功能，并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数（IMF），然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。(The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear.)
