说明：  对图像进行处理后常需要计算图像的PSNR值和NC值(calculate the PSNR and NC of pictures)

系统介绍了MATLAB7.0的基本功能，并设计了丰富的实例(MATLAB7.0 system introduced the basic functions and design a wealth of examples)

matlab温度程序，代码很多，写的很详细，耐心看应该很有用(matlab dimensional temperature program, the code is very detailed, some difficulty, patiently watching might understand)

线性调频脉冲压缩过程中所有仿真结果和代码(Chirp compression process simulation and code all)

使用快速傅里叶变换fft实现带有高斯白噪声的频谱估计(Using fast Fourier transform fft achieve spectrum estimation with Gaussian white noise)

多个脉冲积累后可以有效地提高信噪比，中频积累时要求信号间有严格的相位关系，即信号时相参的，所以称为相参积累。(Multiple pulse accumulation can effectively improve SNR, if integration requires strict phase relationship between signals, whereby the signal coherent, so called coherent accumulation.)

卡尔曼滤波在MATLAB上的实现，本例子是常数型卡尔曼(Kalman filter implemented in MATLAB, and this example is the constant Kalman)

Semi-grand ensemble simulations and Gibbs-Duhemintegration

说明：  这是一个用simulink搭建的经典的跳频模型，对了解跳频有一定的帮助，模型，调试过了，没有问题。(This is a FH model in simulink.)
