本文提出了一种适用于低轨卫异扩频通信系统的多普勒频移快捕方法.该方法基于数字匹配滤波器及自动频率控制环路_利用数字匹配滤波器的囚码快捕特性及其输出主相关峰值对频偏的敏感性，缩短多普勒频移的 捕获时间.论文首先推导了多普勒频移的平均捕获时间表达式，然后根据数值分析结果得到了准最佳捕获判决策略，最后通过比较验证了该快捕方法相对于传统串行捕获方法在性能上的提高. (This paper presents a low-orbit health for different spread spectrum communication system fast catching the Doppler shift method, which based on digital matched filter and automatic frequency control loop _ prisoners using digital matched filter code features rapid acquisition and the output of the main correlation peak frequency deviation of the sensitivity of the Doppler frequency shift to shorten acquisition time. paper first derive the mean Doppler shift acquisition time expression, then the numerical results obtained quasi-optimal capture decision strategies, and finally verified by comparing with the rapid acquisition method to capture the traditional method of serial improvement in performance.)

在完成matlab的基本文件读写功能基础上，绘制等值线以及动画等。共有两个代码，其一为从一文本文件（.txt）中读取数据 ，勾画平面等值线，另外一个从一个文本文件汇总读取数据，制作动画。(After completing the basic matlab file read and write functions, based on the contour map and animation. There are two codes, one from a text file (. Txt) to read data, outlined planar contours, another one from a text file to read data aggregated to produce animation.)

无参数估计方法程序，主要用于统计上的估计方法(Nonparametric EMW test)

说明：  一个很好的东东哦 希望大家来看和下栽哈(a good Dongdong Oh, and hope that we look at Kazakhstan crashed)

一个计算单极子天线表面电流的小程序，需要调试！(a calculated monopole antenna surface currents in small procedures, require debugging!)

五点三次法实现振动信号趋势项的消除， 1、 计算出数据的均值、均方值、方差 ； 2、 用matlab编制五点三次法消趋势项程序。 3、 在同一坐标下绘出消趋势项前后时域信号，并分析比较。 绘出消趋势项前后信号的自相关函数。( Five points three times a method to achieve the elimination of the trend of the vibration signal, 1, to calculate the mean of the data, the mean square value, variance 2, the preparation of the five points three times France extinction trend procedure using matlab. 3, plotted in the same coordinate consumer trends before and after the time-domain signal, analyzed and compared. Draw to eliminate the trend before and after the signal autocorrelation function. )
