用于描述谐波叠加法，可以修改参数已完成要做的叠加！(Used to describe the harmonic superposition method, you can modify the parameters to do the overlay has been completed!)

小波变换的实例，直接放在MATLAB里就可以运行，但需要换入自己的图片(Wavelet transform instance, can be placed directly inside MATLAB to run, but needs to be replaced into its own image)

This is a MATLAB® instrument driver for use with v2.0 of the Instrument Control Toolbox™ and higher. It supports the Agilent E3647A power supply.

说明：  拉普拉斯高斯算子 拉普拉斯—高斯算子（Laplacian of Gaussian算子，通常缩写为log算子）是一种二阶微分算子，将在边缘处产生一个陡峭的零交叉。(Laplace Gaussian operator Laplace- Gaussian operator (Laplacian of Gaussian operator, often abbreviated as log operator) is a second-order differential operator, will be generated at the edge of a steep zero crossing.)

伪zernike矩变换，计算图像的伪Zernike矩并作为特征。(Pseudo zernike moment transformation, the image of the pseudo-Zernike moments calculated as features.)

线性调频信号是典型的脉冲压缩信号，在雷达波形设计中要重要的作用。本实例给出了调频雷达中混入正弦波噪声和高斯噪声时如何抑制噪声从而恢复调频信号的过程(LFM signal is a typical pulse compression signal, the radar waveform design to an important role. This example shows the sine wave frequency modulated radar mixed with noise and Gaussian noise, how to suppress the noise FM signal to the process of recovery)
