A Normal Mode Reverberation and Target Echo Model to Interpret Towed Array Data in the Target and Reverberation Experiments /

Their input voltage to deployed 1.2 m off the bottom, about 3-mW of the midpoint of the signal generator was flat; so the output levels followed the the FORA array. [...] On every malized” to a prediction from the Clutter Model, with the overall second pulse, the echo repeater responds, retransmitting the level of the data adjusted to agree near the array. [...] The agreement of the model and data along the Reverberation Track to the SE is reasonably good; the 3 model inputs, and striations in the reverberation along the Re- The vertical line at 3.6 s is from the PAT vertical air hose, which is near the ambiguous beam and due to its ∼10–15-dB target strength spills over into this verberation Track will be discussed in more detail in Section IV. [...] The model was run at 3450 Hz and The data, however, show the opposite behavior with respect the omnidirectional results were reduced by the effective rever- to the bathymetry. [...] The same bottom half space as in the previous ric fluctuations around the 19-m mean surface, and the green calculation was used, but the Lambert coefficient was adjusted curve the slope of the bathymetry.
