The paper points: frequency stability of the pulse modulation wave well used the power spectrum density function to indicate, not Allan variance. A new middle frequency spectrum analysis frequency stability measurement method on band pass sample technique was put forwarded.
本文主要阐述了脉冲调制信号频率稳定度的时,频域表征方法,指出脉冲调制波频稳宜用相对单边功率谱表征,而不宜用阿仑方差表征;提出了一种新的基于带通采样的中频频谱分析法,导出了系统设计公式,建立了一个脉冲调制波频稳测试实验系统;以Delphi7.0为软件开发工具,采用模块化和面向对象的设计思想完成了脉冲调制信号相噪测试系统软件的研制。

In many cases, Allan variance has to be measured with dead time and then modified with Barnes bias function.
在很多场合只好用有间隙采样做阿仑方差,然后用巴勒斯偏函数加以修正,其繁杂程度是可想而知的。
Finally, the Allan variance is used to analyze the noise characteristics of radiometer system output signals. And performance parameters are measured and measurement results are analyzed.
最后,利用艾伦方差对辐射计的输出信号进行了噪声分析,并进行了辐射计性能参数测试,对实测数据进行分析处理后得出辐射计的参数测试结果。
