摘要

本研究采用双传感器对热声辐射进行了相关接收。实验采用不同带宽的接收器，改变热源的大小和热源到接收器的距离，并在垂直于系统声轴的横向方向上移动热源。应用射电天文学中的关系式，对每一种情况计算了热声辐射的相关函数。结果表明，在考虑测量误差的情况下，实验得到的相互关函数与计算得到的相互关函数接近。

Verification of Relations Obtained in Radio Astronomy for Correlation Reception of Thermal Acoustic Radiation

In this study, correlation reception of thermal acoustic radiation by a pair of sensors was carried out. The experiment used receivers with different bandwidths, varied the size of the heated sources and the distance from the sources to the receivers, and also shifted the sources in the transverse direction perpendicular to the acoustic axis of the system. For each case, applying the relations used in radio astronomy, the correlation functions of thermal acoustic radiation were calculated. It is shown that the experimentally obtained and calculated cross-correlation functions are close, taking into account the measurement error.
