贝叶斯频谱估计算法在测量人工传输线长度中的应用
The Application of Bayesian Spectral Estimation in Measuring the Artificial Transmission Line
【摘要】 首先通过公式的推导给出贝叶斯频谱估计的基本思想,然后结合一个人工传输线长度测量的具体实例介绍了如何在实际中运用此估计方法,并与传统方法进行了简单的比较。结果表明,此算法的精确度优于传统算法。
【Abstract】 Bayesian spectral estimation is applied to estimate the length of an artificial transmission line. The interval between successive peaks of the graph of frequency versus voltage is measured and the reflection theory is used to calculate the cable length. Comparison with the traditional method shows improved resolution.
