星间激光干涉仪中频载波跟踪环路设计及仿真
|
摘要
基于星间激光干涉仪测距系统激光载波的高动态特点,为了有效地跟踪该测距系统经激光干涉和光电转换后产生的高动态中频测距载波,提出了一种锁频环辅助锁相环的中频载波跟踪算法。环路鉴别器采用二象限反正切鉴相器和四象限反正切鉴频器。经仿真验证,该跟踪算法为星间激光干涉仪高动态载波跟踪提供一种解决方案。
In order to effectively track the high dynamic and intermediate frequency range carrier,a medium frequency carrier tracking algorithm based on the frequency locked loop assisted phase locked loop is proposed,based on the high dynamic characteristics of the laser carrier carrier.The loop discriminator adopts two quadrant counter tangent phase detector and four quadrant arc tangent discriminator. The simulation results show the algorithm provides a solution for high dynamic carrier tracking of inter-satellite laser interferometer.
