简单来说，卡尔曼滤波器是一个"optimal recursive data processing algorithm（最优化自回归数据处理算法）"。对于解决很大部分的问题，他是最优，效率最高甚至是最有用的。(In short, the Kalman filter is an " optimal recursive data processing algorithm (optimal autoregressive data processing algorithm)." For most of the problems to solve it, he is the best, most efficient or even useful.)

调制信号识别，利用设计的算法识别出调制信号。(Modulated signal identification, the use of algorithms to identify the design modulated signal.)

对采集到的信号进行快速傅里叶变换，可以实现对信号频谱分析(The collected signals fast Fourier transform, spectral analysis of the signal can be achieved.)

运动目标模拟器相参性分析，分析了基于数字射频存储器(DRFM)的运动目标模拟器(MTS)相参性。由于DRFM延时的离散性,引起了MTS输出信号相位的改变,破坏了信号的相参性,使MTS输出信号频谱发生变化,不仅使谱线位置移动,而且还产生了附加的寄生谱线。分析结果表明,延时更新率(Fc)决定了谱线间隔,并通过sinc函数决定谱线的幅度,而雷达信号频率与所模拟目标的速度共同决定谱线的移动。 (Moving Target Simulator Coherent Analysis, Moving Target Simulator (MTS)-based digital radio frequency memory (DRFM) coherent. Due to the the DRFM delay discrete MTS output signal of the phase change is caused, the destruction of the phase of the signal parameters, the MTS output signal spectrum changes, not only the spectral line position, but also generates additional parasitic spectral line. The analysis results show that the delay update rate (Fc) determines the spectral interval by sinc function determines the amplitude of the spectrum, while the radar signal frequency and speed together determine the movement of the spectral lines of the simulated target.)

说明：  基于神经网络的PID源程序 可用于学习!!(PID based on neural networks can be used to study the source code!!)

K150 - DIYpack25ep for windows 7

It is a very useful matlab program to plot a 3D graph by using sfunction and it shows how to use multiplexur for x, y and z signals. Enjoy it and good luck.
