%description
Acoustic target strength (TS) represents the intensity of an echo
returning from an individual scatterer such as bubbles, fish, or
zooplankton. TS can be used to convert integrated or volumetric
backscatter collected from fisheries acoustic surveys into units of number
density (e.g. animals per m^3), abundance (e.g. number of animals), and
biomass (e.g. kg). This parameter can also be used to aid in classifying
backscatter, such as separating likely echoes of large predatory fish
(e.g. adult cod) from smaller prey (e.g. shrimp). One way to estimate TS
is to use physics-based models to calculate theoretical TS that comprise
exact and approximate solutions as well as analytical approaches. The
models provided can help provide TS estimates over broad statistical
distributions of model parameters. Applications are described by Lucca et
al. (2023) <doi:10.1121/10.0022459>, with fisheries-acoustics principles
from Simmonds and MacLennan (2005) <doi:10.1002/9780470995303>.
