实验代码
由于卫星与用户接收机二者的连线方向上存在相对运动，因此引起了载波和伪码的多普勒效应，再加上接收机晶体震荡频率漂移和卫星时钟频漂等原因。接收机实际接收到的卫星载波中心频率一般不再等于信号被发射时的标称频率，这就需要接收机在载波频率一维对信号进行搜索。同时，由于卫星到接收机的距离时刻变化，加上接收机始终相对于GPS时间的偏差又并不固定，因而接收信号的伪码相位值也在改变，所以接收机也要在码相位一维对信号进行搜索。扩频信号的捕获是一个对目标信号频率域和相位域进行的二维搜索过程。(Because of the relative motion between the two of the satellite and the user receiver, the Doppler effect of the carrier and pseudo-code is caused, and the frequency drift of the oscillation of the receiver crystal and the frequency drift of the satellite clock are added. The frequency of the satellite carrier center that the receiver actually receives is generally no longer equal to the nominal frequency of the signal being transmitted, which requires the receiver to search the signal in one dimension of the carrier frequency. At the same time, because the distance between the satellite to the receiver is changed, the deviation of the receiver always relative to the GPS time is not fixed, so the pseudo code phase value of the received signal is also changing, so the receiver also searches for the signal in the code phase. The acquisition of spread spectrum signal is a two-dimensional search process for the frequency domain and phase domain of the target signal)

说明： 普通显示技术是根据几何光学成像原理，记录下光波的振幅，将空间物体成像在一个平面上。由于丢失了光波的相位信息，因而物体的信息是不完整的。全息图因能够完整地记录物光波的振幅和相位，因而能够包含物体的全部信息。菲涅耳全息术作为全息术的一个分支，更是得到了飞速的发展，已经广泛应用于全息干涉计量术、全息存储、全息光学组件、全息显微术等各个领域。
本论文主要研究菲涅耳全息图的编码与显示过程。经典光全息术包括波前记录和波前再现两步。全息波前记录将物光和参考光以干涉条纹记录成全息图，此全息图同时记录了物光波的振幅和相位 然后用参考光照射全息图，该参考光经过衍射后，即可再现出原始物体。
计算全息是将先进的计算机技术和光全息术结合起来，利用计算机产生全息图。它不需要物体实际存在，而是把物波的数学描述输入计算机处理后，绘制出全息图，然后用光学方法重现。本文采用计算全息方法,利用Matlab模拟光线的菲涅耳衍射传播,用计算机生成菲涅耳全息图 ,并由所生成的全息图再现出原始图像 ,完成全息图的数字再现。
