【摘要】：插值法是离散频谱校正分析中应用最为广泛、研究最为深入、算法种类最多的一种校正方法,按照采用的谱线类型又可以分为基于幅值谱比值和基于复数谱比值的两种插值法。在实际工程应用中,抗噪声性能是评价一种算法最为重要的指标之一。在回顾国内外插值校正算法的理论研究和发展现状的基础上,简要介绍了各种插值算法的原理和特点。通过仿真考察了各算法的抗噪声性能,重点分析了插值极性错误对目前各种算法的影响。通过分析比较,指出了现有插值法的不足之处和亟待解决的问题,对插值校正算法的发展进行了展望和探讨。
[Abstract]:Interpolation is one of the most widely used, deeply researched and widely used methods in discrete spectrum correction analysis. According to the spectral line types, it can be divided into two kinds of interpolation methods based on amplitude spectrum ratio and complex spectral ratio. In practical engineering application, the anti-noise performance is one of the most important indexes to evaluate an algorithm. On the basis of reviewing the theoretical research and development status of interpolation correction algorithms at home and abroad, the principle and characteristics of various interpolation algorithms are briefly introduced. The anti-noise performance of the algorithms is investigated by simulation, and the influence of interpolation polarity errors on the current algorithms is analyzed. Through analysis and comparison, this paper points out the shortcomings of the existing interpolation methods and the problems to be solved urgently, and prospects and discusses the development of the interpolation correction algorithms.
