| 摘要: |
| 以往的文献中,多用群时延来分析TT＆C的测距误差,这种方法不够准确和全面.本文采用幅、相频率特性和相位波动特性来分析TT＆C信道中的测距误差.详细讨论了由于信道频率特性和相位波动特性变化产生的测距误差,给出了测距侧音相位的数学表达式.运用这些公式可以计算出这些因素对测距漂移误差的影响,提高测距精度. |

| () |
| Abstract: |
| Many published papers analysed range error by using group delay,it is not accurate enough.This paper uses frequency character and phase fluctuating character to analyse range error of TT&C systems,and gives out formulas.Using these formulas,the factors that having influence on range error can be calculated and range accuracy can be improved.Above conclusion has been tested and applied in TT&C systems for years. |
