包络检波

Finite-difference time-domain (FDTD) is a popular computational electrodynamics modeling technique. It is considered easy to understand and easy to implement in software.

线性调频信号的速度多普勒模糊函数，有三维以及二维截面图(The speed of linear frequency modulation signal doppler fuzzy function, there are three dimensional and two dimensional section graph)

matlab支持向量机回规界面，操作简单，使用方便(Matlab Support Vector Machine to back regulatory interface, simple operation, easy to use)

基于FFT的伪码捕获，并且非相关累加使之工作在更低信噪比条件下。(FFT-based pseudo-code acquisition, and non-work related cumulative so that at lower SNR.)

说明：  完全自主实现的神经网络代码，对于深刻理解神经网络和BP算法很有帮助。(The neural network code, which is implemented autonomously, is very helpful for us to deeply understand the neural network and BP algorithm.)

利用傅里叶变换，从理论上实现了混合信号的频谱分析，能够反应信号的真实频率及其幅值 (Fourier transform theory, mixed-signal spectrum analysis, to reflect the true frequency and amplitude of the signal )

做信号处理的时候经常会用到FFT，而MATLAB自带的FFT只能变换出一列系数，想做成频谱图还要自己加一部分，自己写了一个小程序，输入原始信号和采样率，可以画出标准的幅值谱和功率谱。(Do signal processing is often used when the FFT, and FFT MATLAB own transformation from a coefficient of only wanted to make Canada part of the spectrum but also their own, to write a small program, the input original signal and the sampling rate can be Draw a standard amplitude spectrum and power spectrum.)
