Comparison of Synthetic and Experimental Bottom Interactive Waveforms
Our interest in subbottom acoustics is motivated by proposed continuous wave (CW) passive systems designed to utilize more than just the energy content of signals arriving at the receiver via predominantly bottom bounce paths. To reach a point where the merits of such systems could be delineated with confidence or contributions to their conception could be made, it was first necessary to have a believable theoretical model capable of predicting the received waveform versus time produced by a transient source. The apparent contradiction that while the system concepts pertain to CW signals, the model is required to accommodate transient signals can be explained from the belief that the highest quality bottom bounce data is obtained from transient sources such as air guns or explosives thus achieving credibility for the model implies assessment against transient data.
