DISCLAIMER

Federico Guerra and SIGNET lab do not endorse or recommend the use of any of the transducer listed below.
The copyright and property of of each transducer design is retained by the respective owners. The specifications of each transducer have been inferred from the transducer data sheets courtesy of the respective owners.
The list below is to be taken as a best-effort list, meaning that data has been taken from publicly avalaible documents, at the programmer's discretion.
This list is NOT final and will undergo continuous changes, aimed at providing support for an increasing number of transducers in WOSS.
If you would like any specific, not currently supported transducer to be included in WOSS, please feel free to contribute by sending transducer data (in the format mentioned below) to nsmir.nosp@m.acle.nosp@m.-user.nosp@m.s@de.nosp@m.i.uni.nosp@m.pd.i.nosp@m.t.

WOSS accurately simulates power consumption, Sound Pressure Level (SPL) output, and vertical beam pattern of real acoustic transducers.

Transducers can be imported into simulation, and their beam pattern can be rotated or modified with a additive and a multiplicative constant to better suit the user needs.

Furthermore, woss::Location, WossPosition and WossWpPosition support simulation of dynamic orientation of the associated transducer to better simulate how AUV movements impact on transmission.

See also: woss::Location, WossPosition, WossWpPosition

Finally UwMPhyBpskTransducer and WossMPhyBpsk now supports array of transducers to permit spectral optimizations with realistic power computations and ray attenuation.
