Compact representation of temporal processes in echosounder time series via matrix decomposition
We developd a data-driven methodology based on matrix decomposition to build compact representation of long-term echosounder time series using intrinsic features in the data.
Echo statistics associated with discrete scatterers: A tutorial on physics-based methods
From basic foundational concepts to advanced topics in modeling the statistics of echoes from discrete scatterers, inspired by sonar observation of marine organisms.
Macroscopic observations of diel fish movements around a shallow water artificial reef using a mid-frequency horizontal-looking sonar
Mid-frequency sonar provides a first-of-the-kind macroscopic observation of the nightly foraging runs of fish inhabiting a shallow-water artificial reef in northern Gulf of Mexico.
Tongue-driven sonar beam steering by a lingual-echolocating fruit bat
Experimental measurements and theoretical modeling provided insights into the mechanisms by which tongue-clicking fruit bats change their echolocation sonar beam direction without changing head aim or mouth shape.
Can the elongated hindwing tails of fluttering moths serve as false sonar targets to divert bat attacks?
The weak but persistent echoes from the hindwing tails of luna moths may help them confuse the sonar-guided bat predators, even though the tail echoes themselves are not strong enough to completely distract the bats' attention.
