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.
