层次分析法！改进的判断矩阵一致性检验 进行矩阵一致性度量的方法主要有两种，一种是由T.L.Saaty提出的一致性比率法C.R.(Consistency Ratio)[13]。还有一种是由Crawford与Williams提出的基于行几何平均法(Row Geometric Mean Method)的几何一致性指标GCI(Geometric Consistency Index)[14]。我们采用的是第一种方法：一致性比率法(C.R.)。(The analytic hierarchy process! Judgment matrix consistency test improved)

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.)

该代码为多频外差四频相移的原理程序，开发环境为MATLAB,可以帮助初学者快速了解外差法的原理。(The code on multiple frequency heterodyne principle of four frequency phase shift process, development environment of MATLAB, can help beginners to quickly understand the heterodyne principle. )
