Passive seismology is becoming increasingly popular for glacier/ice-sheet structure investigations in Polar regions. Single-station passive seismic methods including P-wave receiver functions (PRFs), horizontal-to-vertical spectral ratio (HVSR) and a recently proposed autocorrelation method have been used to retrieve glacier/ice-sheet structures. Despite their successful applications, analysis regarding their detection abilities in different glaciological environments has not been reported. In this study, we compare ice thicknesses and vp/vs ratios obtained from the three methods using data collected at GAMSEIS and POLENET/ANET seismic arrays in Antarctica. Ice thickness estimates derived from the three methods are found to be consistent. Comparisons conducted under various model setups, including those involving tiled layers and sedimentary layers, show that the effectiveness of the autocorrelation method is not superior to the PRF method for retrieving ice-sheet structures. The autocorrelation method however can complement other methods as it only requires a single component seismic record.

P波尾波自相关法反演的南极冰盖结构及与其他两种单站被动地震法的比较

被动地震学在极地地区的冰川/冰盖结构研究中变得越来越流行。单站被动地震方法包括 P 波接收函数 (PRF)、水平垂直谱比 (HVSR) 和最近提出的自相关方法已被用于检索冰川/冰盖结构。尽管它们的应用很成功，但关于它们在不同冰川环境中的检测能力的分析尚未见报道。在这项研究中，我们比较了冰的厚度和vp/vs使用在南极洲的 GAMSEIS 和 POLENET/ANET 地震阵列收集的数据从三种方法获得的比率。发现从这三种方法得出的冰厚度估计是一致的。在各种模型设置下进行的比较，包括那些涉及瓦片层和沉积层的模型设置，表明自相关方法的有效性并不优于 PRF 方法检索冰盖结构。然而，自相关方法可以补充其他方法，因为它只需要一个单分量地震记录。
