Estimation of Source Location Using Curvature Analysis

A quadratic surface can be fitted to potential-field data within 3×3 windows, which allow us to calculate curvature attributes from its coefficients. Phillips (2007) derived an equation depending on the most negative curvature to obtain the depth and structural index of isolated sources from peak values of special functions. They divided the special functions into two categories: Model-specific...

Location, location, location: finding a suitable home among the noise.

While sound is a useful cue for guiding the onshore orientation of larvae because it travels long distances underwater, it also has the potential to convey valuable information about the quality and type of the habitat at the source. Here, we provide, to our knowledge, the first evidence that settlement-stage coastal crab species can interpret and show a strong settlement and metamorphosis resp...

Transient Noise Source Localization

Conventional beamforming systems for noise source localization are mostly based on frequency domain calculations. Additionally, narrowband assumptions concerning signal characteristics are often made to simplify the calculations, i.e. to be able to express a single time delay as a sole phase shift in the frequency domain as well. If necessary, a broadband system is then modeled as a composition...
