Research on tracking stability of telemetry antenna based on variation

摘要:

对遥测系统伺服跟踪数据进行处理，分析对比几种跟踪方式，指出几种跟踪方式中可能存在的问题，并提出相应的改进措施。同时，通过曲线变差、方差的属性分析，研究自主跟踪时天线俯仰、方位的稳定度与跳变程度， 并与理论弹道、数字引导方式的曲线稳定度进行分析和对比，得出变差越大稳定度越差，方差越大异常跳变越明显的结论。

Abstract:

This paper deals with servo tracking data of telemetry system, analyzes and compares several tracking methods, points out the possible problems in several tracking methods, and puts forward corresponding improvement measures. The stability and jump degree of antenna azimuth and elevation angle during autonomous tracking are studied through the attribute analysis of curve variation and variance. We analyze and compare with the curve stability of theoretical trajectory and digital guidance. The conclusion is that the greater the variation, the worse the stability, and the bigger the variance, the more obvious the abnormal jump.
