摘要：

The problem of acoustic backscattering from suspended particulates in the near field of a piston source is examined. A monostatic configuration is used, with the transducer acting as a transceiver. Predictions for the range dependence of the backscatter signal are calculated, and formulated into a nondimensional general form. To compare predictions with observations, a series of laboratory experiments, using a number of transducers insonifying varying homogeneous suspensions, has been conducted. To first order the outcome shows good agreement between prediction and observation.© 1995, Acoustical Society of America. All rights reserved.
