One of the applications of the acoustic reflectometry technique is to study the layered media structures such as soil, snow. The issues of acoustic reflectometry system to study the layered media structures related with using non-ideal components are given in this paper. It has been demonstrated that there are several artifacts present in the acoustic reflectometry analysis in practice. The paper presents the signal processing algorithms to compensate the effects of non-ideal components of an acoustic reflectometry system. We have developed the signal processing techniques using inverse filtering to compensate for the artifacts due to the non-ideal nature of the transmit–receive chain. The effectiveness of the inverse filter to compensate the artifacts is also tested. The application of the acoustic reflectometry system after artifacts compensation to study the layered structures has been demonstrated using experiments conducted in a full anechoic room.

声反射仪系统中由于非理想成分引起的伪像的补偿技术
声反射法技术的应用之一是研究分层的介质结构,例如土壤,雪。提出了利用声反射法研究与非理想成分有关的分层介质结构的问题。已经证明,在实践中,声反射法分析中存在一些伪像。本文提出了信号处理算法,以补偿声反射仪系统中非理想分量的影响。由于收发链的非理想特性,我们已经开发了使用逆滤波来补偿伪像的信号处理技术。还测试了逆滤波器补偿伪像的有效性。
