高动态跳扩频测控信号的捕获仿真研究
Simulation of High Dynamic DS/FH Spread Spectrum Signal Acquisition
摘要
为了达到跳扩频信号的快速捕获的目的，基于MATLAB/SIMULINK平台，采用等待搜索跳频捕获和匹配滤波器直扩捕获方法，进行了DS/FH系统捕获的仿真。在对等待搜索跳频捕获和匹配滤波器直扩捕获原理分析的基础上，建立的捕获模型，对系统的工作过程进行分析，并且在模型中加入了多普勒频移，使得系统能够运用于测控领域。仿真结果表明，匹配滤波器直扩捕获可以在一个跳频时隙内完成捕获，从而引导跳频端同步跟跳，满足系统要求。Abstract
In order to achieve rapid acquisition of DS/FH Spread Spectrum Signal,based on MATLAB / SIMULINK platform ,wait scanning and matched filter methods are introduced to finish the simulation of DS/FH system.Based on analyzing the two methods, establish the acquisition model,analyze the process of the system,and with the Doppler frequency introducted,it's possible to be available in TT&C.The result shows that signal can be captured in one FH slot which meet the system requirements. 关键词
