1．编写一个程序，读取一句英语短语，并将其编制成莫尔斯码 莫尔斯码是世界上最著名的编码机制，是1832年由Samuel Morse创立的，用于电报系统使用。莫尔斯码编码规则如下：①字母、数字和一些特殊符号（如圆点、逗号、分号）用一系列指定的点和线表示；②单词之间用三个空格分开，没有点和线；③编码字母之间用一个空格。 (1 write a program to read a word, English phrases, and programmed into the Morse code Morse Ma is the encoding mechanism of the world s most famous, is in 1832 by the Samuel Morse foundation, used for telegraph system. Morse coding rules are as follows: ① letters, numbers and special symbols (such as dot, comma, semicolon) is represented by a series of specified points and lines the words are separated by three spaces, no point and line the code letters with a space. )

生成一段线性调频信号，并用脉冲压缩技术对信号进行接收，得到脉冲的时延信息(Generate a linear FM signal, and pulse compression technology to receive the signal pulse delay)

说明：  本程序采用传统的snake模型，改进后通过双线性实现彩色图像放大，效果良好(The program uses the traditional snake model, improved by bilinear achieve color image to enlarge, to good effect)

，建立车体6个自由度加上前轮转向系统1个自由度的汽车数学模型；该汽车数学模型不需引入很多的人为假设；可以实现给定汽汽车前轮转角，也可以不给定前轮转角；不依赖需要复杂测定的侧向力函数及相关模型参数；考虑了轮胎的滚动特性 已通过测试。 (Vehicle mathematical model of one degree of freedom, the establishment of the body' s six degrees of freedom coupled with front-wheel steering system mathematical model of the car does not need to introduce a lot of people assume front wheel angle can be achieved given steam can also be given front wheel angle does not depend on the complex determination of the lateral force function and model parameters consider rolling characteristics of the tire has been tested.)
