啁啾脉冲对传输特性的影响，用MATLAB实现可视化(chirp pulse)

说明：  matlab科学计算继续上传，一共10个章节，由浅入深，几乎包括了绝大部分的科学计算方法以及仿真。本人把部分算法做了优化，更为完善，一共十二个，其中11、12是本人与实验室搭档共同编写，感谢王美女(matlab scientific computing continue to upload a total of 10 chapters, easy-to-digest, almost including most of the scientific method of calculation and simulation. I have done some algorithm optimization, a more perfect, a total of 12, 11,12 which is my partner, prepared jointly with the laboratory, thanks to Wang Mei)

有两个程序一个是关于frft的源程序，一个是应用frft对线性调频信号进行检测的程序，原理是以变换阶数（不同的分数阶域）为变量对观测信号进行分数阶变换，形成信号能量在时频平面上的二维分布，在此平面上按阈值进行峰值点的二维搜索即可检测线性调频信号并估计其参数。(There are two procedures one on frft the source, one application frft linear FM signal detection process, the principle is to transform the order of (different fractional domain) as the independent variables on the observed fractional signal change, the formation of signal energy in two-dimensional time-frequency plane distribution in this plane, the peak threshold value by two-dimensional linear FM signal can be detected search and estimate its parameters.)

分析了BFSK的性能及原理，并利用matlab仿真实现其误码率等信息。写成word文档，后面附有源程序。(BFSK performance analysis and principle, and use matlab simulation to achieve its bit error rate information. Word document written in the back with a source.)

,在强干扰中提取信号,不仅要求有一定的信噪比,而且必须对信号作恒虚警处理.在自动检测系统中,对一定的检测门限来说,当干扰电平增大几分贝,虚警率就会大大增加,致使显示器画面饱和或计算机过载,这时即使有足够大的信噪比,也不可能做出正确的判决.为此在自动检测雷达中,必须具备恒虚警处(, extracting signal in strong interference, not only requires a certain signal-to-noise ratio, and must make constant false alarm processing for signal. In the automatic detection system, for a certain detection threshold, when the noise level increases, a few decibels will greatly increase the false alarm rate, led display screen saturated or computer overload, even if there is enough SNR at this moment, it is impossible to make the right decision. Therefore in the automatic detection of radar, must have a constant false alarm)
