为了评价GPS信号并行码相位捕获算法、并行频率捕获算法、线性捕获算法3种常见捕获算法捕获性能的优劣，采用Matlab/Simulink工具对其捕获效果进行仿真分析。首先理论分析三种捕获算法的优劣，再用Simulink模拟信号源，M文件实现捕获过程的方式，并以捕获时间作为标准，得出并行码相位捕获所用时间最短，并行频率捕获时间相对较长，线性捕获最慢的结果。这些算法的仿真实现和捕获性能的比较，对接收终端捕获模块的研发工作具有一定的参考与指导作用。

In order to evaluate the capture performance of GPS signal parallel code phase acquisition algorithm, parallel frequency acquisition algorithm, linear acquisition algorithm, this paper simulates these three algorithms by using Matlab/Simulink. First, this paper analyses the merits of these three kinds of capturing algorithm theoretically, then simulates a signal source by Simulink, realizes the capture process by M file. Using the capture time as the standard, paper can get the conclusion that the capture time of parallel code phase is the shortest one, parallel frequency capture is second, linear capture is the slowest algorithm. The simulate implementation of these algorithms and the comparison of capture performance have some reference and guidance on the receiving terminal capture module development work.
