互模糊函数(CAF)在分布式卫星信号接收中的应用

Cross Ambiguity Function(CAF) in Distributional Satellite Signal Receive Application

文章提出采用基于互模糊函数(CAF)的时间差和频率差联合估计法,可准确地对分布式卫星信号接收中的时间差和频率差进行估计,有效地抑制了背景噪声的影响。在估计性能方面,该方法优于基于相关的方法。文章最后使用计算机仿真验证了文中的结论。

This article proposed uses based on mutually the Cross Ambiguity Function（CAF） time difference and the frequency difference union estimate law, but accurately carries on the estimate to in the distributional satellite signal receive time difference and the frequency difference, has sup- pressed the background noise influence effectively. In the estimated performance aspect, this method surpasses based on the related method. The article finally used the computer simulation to confirm in the article conclusion.
