摘要
介绍了卫星通信地球站天线跟踪精度的定义和目前通用的测量方法,并用射击实例来对跟踪精度的定义和测量方法的精确度进行了分析和讨论。目前通用的测量方法给出的只是跟踪精度的一部分,没有完全覆盖跟踪精度定义所表达的内容。在此基础上提出了跟踪精度测量和计算方法的新见解,并计算天线跟踪准确度的测量不确定度。
The paper introduces the definition and present common measuring method of antenna tracking accuracy in satellite communication earth stations.The definition and the accuracy of measuring method are analyzed and discussed.The present common measuring method provides only a part of tracking accuracy and can not completely cover all the contents of the definition.Then,based on these methods,a new view is put forward about tracking accuracy measuring and calculation.Finally,the measuring indeterminacy of antenna tracking accuracy is calculated.
