“…it is not possible to infer results from one drop rate to another. However, Gregg, et al, 13 report results for several drop rates near 1.0 m/sec, showing that the power transfer function plotted in k' space does not change dramatically with drop rate. We may conclude that the value of the transfer function will be somewhat changed under operational conditions, but will still allow a good signal-to-noise ratio for the sensed signal.…”
