Vertical scanning of beluga sonar beam.
Distribution of the received level (RL; represented via color spectrum) for each hydrophone for 41 clicks in 5 seconds, demonstrating vertical scanning of the array. Filled circles signify clicks where the hydrophone with the maximum RL was received by one of the outermost receivers and therefore wa...

Distribution of the received level (RL; represented via color spectrum) for each hydrophone for 41 clicks in 5 seconds, demonstrating vertical scanning of the array. Filled circles signify clicks where the hydrophone with the maximum RL was received by one of the outermost receivers and therefore was directed towards the edge of the array. |
