说明：  详细介绍数字信号处理及MATLAB应用实现的书籍(Detailed application of digital signal processing and MATLAB realization of the books)

Rife是一种频谱校正方法，分别给出了以上算法的Matlab程序并且画出了图形。( Rife is a spectrum correction method given above algorithm Matlab program and draw graphics.)

雷达采用匹配滤波完成脉冲压缩，采集频率fs=420MHz,仿真雷达回波，并绘出加Hamming窗前后的脉压波形。目标如图所示由(-5，-2)，(0，5)和(6,-7)三个散射点组成,散射强度分别为（1，2，5）,雷达位于（-5000,0）处(The completion of the radar pulse compression using matched filtering, collecting the frequency fs = 420MHz, simulation of the radar echo, and draw the Hamming window plus post-pulse pressure waveform. Targets as shown by (-5,-2), (0,5) and (6,-7) three scattering dots, scattering intensity, respectively (1,2,5), radar at (-5,000, 0), Office of)

Octave 3.2. Linear regression, cost function, minimun search.

matlab非线性kalman滤波工具箱，包括了ukf,pf等等，很好用(nonlinear kalman filter matlab toolbox, including ukf, pf, etc., very good)

粒子滤波的MATLAB源代码,内有5个独立源代码，带注解 (MATLAB source code particle filter, there are five independent source code, annotated)

利用单应点进行透视反变换，matlab实现(Perspective inverse transform, matlab achieve)
