Data and code routines for biosonar data

Processed Acoustic data, and plotting routines to visualize them, for the paper titled "A dolphin-inspired compact sonar for underwater acoustic imaging.", Communications Engineering, by Hari Vishnu, Matthias Hoffmann-Kuhnt, Mandar Chitre, Abel Ho and Eszter Matrai.

If using this data, please cite the paper above.

To obtain the  output visualizations for the acoustic data recorded during the echoic-to-visual matching-to-sample trials (plots shown in Figs. 3, 5, and Supplementary Fig. 3 in the paper), run Plot_biosonar_output.m

To obtain the output visualizations with biomimetic sonar data (plots shown in Fig. 4 in the paper), run Plot_biomimetic_output.m

These perform the template-matching of acoustic outputs with the shading masks (templates), and give the discrimination coefficient in dB, and plot the acoustic outputs (with the option of plotting the shading masks on top).

Change the variable to 'Bartlett'/'SA' for Bartlett beamformer output or Sparsity-aware beamformer output, and the variable  to SQ/SQset1/SQset2/FF/FFset1/FFset2 as required
