船载测控设备船摇前馈使用意见和改进方法

Suggestions on How to Use and Improve Forward-feed Information of Ship Rocking in Shipboard TT & C Equipment

针对船载测控设备在执行试验任务过程中使用船摇前馈可能存在的问题,提出了船摇前馈的使用意见。另外,为了增强船摇前馈使用的安全性,又对船载测控设备的研制改造提出了两种改进方法:一种方法是通过数字低通滤波器滤除船摇前馈数据中的高频分量,从而可以有效抑制数据跳变对跟踪的影响;另外一种方法是设计一个简单有效的剔除野值的判据,当出现少量野值时则进行野值剔除,当出现大量野值时则自动取消船摇前馈的使用。

Aiming at potential problems of shipboard TT & C equipments in using forward-feed information of ship rocking,this paper presents some suggestion.To enhance safety,two methods are also presented.The first one is to filter high-frequency component in forward-feed information of ship rocking using a digital lowpass filter,it can overcome data jitter′s influence on antenna tracking.The second is to design a criterion that can eliminate wrong data,when a little wrong data emerges,then eliminate them,when much w...
