This application is used to estimate the longitudinal and transversal sound speeds of a standard sphere used in calibrations of fisheries echosounders, which will lead to improved calibration results and more accurate sensor measurements. The tool interfaces with the Kongsberg EK80 software to subscribe to wideband (FM) data, using either live or replay data. Wideband spectra from the sphere echo are then compared to theoretical results for the given sphere, and a minimization technique used to estimate the sphere sound speeds that best align the measurements.
The software is a Matlab application, and as such is provided in one of two format:
- A Matlab application file (.mlapp) that can be run using a licensed version of Matlab
- A standalone executable that can be run on any computer, with or without Matlab
To use the standalone executable, download and run the file "/release/package/MyAppInstaller.exe" from the Github repository. Follow the instructions which should download and install all the required elements needed to run the application (requires an Internet connection for initial installation).
Use of the Matlab Application file (.mlapp) required having a licensed version of Matlab installed on the machine. If available, download and run the file "SphereSoundSpeeds.mlapp" from the Github repository.
