拉普拉斯金字塔的实现方法工具箱，能用，不过要仔细读读，没什么注释。(Laplacian pyramid of the implementation toolkit, can be used, but should be carefully read, no comment.)

实现合成孔径成像的三种算法，包括RD（距离多普勒）、RMA（距离徙动）、CS（Chirp Scaling）(Three algorithms for SAR imaging, including RD (Range Doppler), RMA (Range Migration) and CS (Chirp Scaling))

此代码是计算两个数据之间的相关性的，直接调用Matlab里的功能函数(This code is to calculate the correlation between the two data directly call Matlab functions)

说明：  PSK信号的同步技术和方法，供信号解调用(PSK signal synchronization techniques and methods for the output signal called)

对线性系统和非线性系统进行的仿真，使之能在较逼真的建模(Of linear systems and nonlinear systems of simulation, so in a more realistic modeling)

题目：已知被控对象为 1/(10s+1)*exp(-0.5s)。假设系统给定为阶跃值r＝30，采样时间为0.5s，系统的初始值r(0)＝0。试分别设计： (1)常规的PID控制器； (2)常规的模糊控制器； 分别对上述2种控制器进行Matlab仿真，并比较控制效果 (Topic: Known charged object is 1/(10s+1)* exp (-0.5s). Assume that the system is given as the step value r = 30, the sampling time of 0.5s, the system the initial values ​ ​ of R (0) = 0. Trial were designed: (1) conventional PID controller (2) conventional fuzzy controller Matlab simulation of the two kinds of controllers, respectively, and compare the control effect)
