出来的图形是混沌图形，但是x，y，z分解后为有规律曲线，与信号类似，说明信号的叠加或许是一种混沌系统(The figure is chaotic, but x, y, Z are decomposed into regular curves, similar to signals, indicating that the superposition of the signals may be a chaotic system.)

空时自适应信号处理(精) 清华大学学术专著图书空时自适应信号处理（STAP）是相 控阵机载雷达杂波抑制与目标检测的关键技术，已成为雷达界研究方向。(Space-Time Adaptive Signal Processing (STAP), the academic monograph of Tsinghua University, is the key technology of clutter suppression and target detection for phased array airborne radar, and has become the research direction of radar field.)

我们在整个游戏中，看到的所有内容，我们都理解为游戏对象。 那么每一个游戏对象，都是由一个单独的类创建而来。 为了便于我们程序的可扩展性，减少冗余代码，我们写一个父类，让这些游戏对象的子类 来继承我的父类，我在父类中，将子类中所共有的成员全部都封装起来。 应该记录游戏对象的横纵坐标 需要记录游戏对象的高度和宽度(All the content we see in the whole game is understood as the object of the game. Then every game object is created by a separate class. In order to facilitate the scalability of our program and reduce redundant code, we write a parent class to let the children of these game objects. To inherit my parent class, I encapsulate all the members that are common in the subclass. The abscissa and ordinate coordinates of the game object should be recorded You need to record the height and width of the game object)
