仿真杂波中目标检测并计算虚警概率与检测概率，比较固定门限与CFAR的区别(1(a): Simulation of target detection 1(b): Evaluation of detection rate and false alarm rate 2(a): Simulation of CFAR detection 2(b): Compare the performance of fix thresholding and CFAR)

说明：  包括跳频通信系统的整个工作流程，调制，跳频，解跳，解调。 忽略同步相关的问题，包括跳频同步，帧同步，定时同步，载波同步等。 其中，调制采用MSK调制方式，解调采用复差分解调方式。(Including the whole work flow of frequency hopping communication system, modulation, frequency hopping, de hopping, demodulation. Ignore the synchronization related problems, including frequency hopping synchronization, frame synchronization, timing synchronization, carrier synchronization and so on. Among them, MSK modulation is used for modulation and complex differential demodulation is used for demodulation.)

坐标转换程序支持计算4参数，7参数和三参数可以实时利用GPS采集当前坐标，进行数据转换可以将转换保存为模板，方便下次直接使用，无需进行繁琐的参数设置(coordinate transformation; coordinate transforming)

桌面弹球是游戏中常见的游戏，从以前的掌上游戏机到如今的手机游戏，都是一个十分经典的游戏。玩家控制一个可以左右移动的挡板去改变运动中小球的移动方向，目的是用小球消除游戏屏幕中的所有障碍物到达下一关，在障碍物被消除的过程中，可能会产生一些能改变挡板或者小球状态的物品，例如：挡板变长、变短，小球威力加强等等。本章主要介绍如何实现一个简单的弹球游戏，让读者了解“动画”的实现原理。(Desktop pinball game is common in game, from the previous game boy to today s mobile games, is a very classic game players control a can move around the damper to change the ball movement direction of the movement, the purpose is to use the ball game screen to eliminate all the obstacles and reach the next level, in the process of obstacle is eliminated, may produce some can change baffle or ball state items, such as: baffle get long become short, ball power to strengthen and so on this chapter mainly introduces how to realize a simple pinball game, let the reader know animation principle )
