共炮点地震记录合成，添加不同比例噪声，进行小波变换去噪处理，得到比较理想的效果(the synthetic seismic record of common shot, add different noise, and do wavelet transform on it, then we can get a better record)

说明：  削减平均最值恒虚警检测器（TMGO and TMSO CFAR）(detectors based on TMGO and TMSO CFAR techniques)

非线性调频信号的产生和脉冲压缩代码，程序中还给出两种不同的脉压系数，用于分析非线性调频信号处理时，脉压结果的应用。(The generation of nonlinear frequency modulation signals and the code of pulse compression are given. In the program, two different pulse pressure coefficients are given. It is used to analyze the application of the pulse pressure results when the Nonlinear FM signal is processed)

对图像中的粒子的近似圆形的衍射光斑通过高斯拟合寻找粒子的实际位置(The image of the particles through the approximately circular Gaussian fitting of the diffraction spot to find the actual location of particle)

独立成分分析(Independent Component Analysis，ICA)是近年来提出的非常有效的数据分析工具，它主要用来从混合数据中提取出原始的独立信号。它作为信号分离的一种有效方法而受到广泛的关注。(Independent component analysis (Independent Component Analysis, ICA) is a very effective tool for data analysis proposed in recent years, it is mainly used to extract the original independent signals the mixed data. It is an effective method for signal separation and widespread concern.)

说明：  辨识参数，进行迭代计算，可以辨识各种经典模型的是参数，经典最小二乘法a(Parameter identification, iterative calculation, can identify all kinds of classical models is the parameter, classical least square method a)
