【摘要】：插值法是離散頻譜校正分析中應(yīng)用最為廣泛、研究最為深入、算法種類最多的一種校正方法,按照采用的譜線類型又可以分為基于幅值譜比值和基于復(fù)數(shù)譜比值的兩種插值法。在實(shí)際工程應(yīng)用中,抗噪聲性能是評(píng)價(jià)一種算法最為重要的指標(biāo)之一。在回顧國(guó)內(nèi)外插值校正算法的理論研究和發(fā)展現(xiàn)狀的基礎(chǔ)上,簡(jiǎn)要介紹了各種插值算法的原理和特點(diǎn)。通過(guò)仿真考察了各算法的抗噪聲性能,重點(diǎn)分析了插值極性錯(cuò)誤對(duì)目前各種算法的影響。通過(guò)分析比較,指出了現(xiàn)有插值法的不足之處和亟待解決的問(wèn)題,對(duì)插值校正算法的發(fā)展進(jìn)行了展望和探討。
[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.
