摘要：该文基于简正波分离识别 Scholte 波的方法，分析了之前 Scholte 波识别水池缩比实验结果中出现较大
误差的原因，提出从声场中优先提取其他阶简正波的方法来改善实验结果、降低实验误差，并证实增加合成孔
径垂直阵采样点数至 119 点 (一次采样期间首末阵元信号保持良好相关性)，有助于改善水池 Scholte 波识别误
差，从而使水池 Scholte 波识别缩比使实验结果与理论值更为接近。水池缩比实验的结果证明该方法改善了
Scholte 波识别实验的结果，降低了声源深度较浅、Scholte 波激发较弱时的实验误差，使水池缩比实验简正波
分离识别 Scholte 波的方法更加可靠。

Abstract: Based on the identification method of Scholte wave using normal wave deposition, this paper an-
alyzes and explains the errors appearing in the previous Scholte wave identification pool scale experiment.
Preferentially extracting other normal waves from the sound field and increasing the sampling points of the
experimental vertical array to 119 points (the signals of the first and last array elements maintain good cor-
relation during one sampling) to reduce the errors and make the results closer to the theoretical results are
confirmed. The results of pool scale experiment demonstrate that these methods improve the results of the
identification experiment of Scholte waves, reduce the errors appearing when the source depth is shallow and
the Scholte wave excitation is weak, and make the method of Scholte wave identification using normal wave
deposition in pool scale experiment more reliable.
