代码说明:

  FFT简称为快速傅里叶变换,是DTF处理的一般实现方法,一维距离成像就是对差拍信号进行FFT变换,变换所得到的幅值图像横坐标为距离信息,纵坐标为幅值信息,通过一维仿真,我们可以看到目标距离相对应的幅值信息。(FFT referred to as fast Fourier transform, is DTF processing general method, a d imaging is difference from pat signal FFT transform)

    对于给定的结构振动响应数据(时间序列信号), 该程序可以分解成多个订单这些响应信号 小波子信号,然后计算出分信号能量spectum。 (For a given structural vibration response data (time series), the program can be decomposed into multiple sub-orders for the response signal wavelet signal, and then calculate the sub-signal energy spectum.)

    说明:  简单利用最小二乘法对缠绕的干涉相位进行解缠,但最小二乘法有个固有缺陷,其是基于全局相位解缠方法,容易造成整体误差扩散。 (Simple least squares method of winding the use of the interferometric synthetic aperture radar (InSAR) to interfere in phase unwrapping)

    orthogonal variable spreading factor (OVSF) is an implementation of Code division multiple access (CDMA) where before each signal is transmitted, the spectrum is spread through the use of a user s code. User s codes are carefully chosen to be mutually orthogonal to each other. These codes are derived from an OVSF code tree, and each user is given a different, unique code. An OVSF code tree is a complete binary tree that reflects the construction of Hadamard matrices.

    A MATLAB M-file which automates this calculation and plots the resulting torque-speed characteristic is shown below. It peIfonns the same steps as part a to detennine the speed for each load current, and then calculates the induced torque at that speed. Note that it reads the magnetization curve from a file called f i g9 _ 9 . ma t. This file and the other magnetization curves in this chapter are available for download from the book s World Wide Web site (see Preface for details).
