  • Title: Multiple-channel dolphin sonar beam characterization
  • Short description:

    The sonar beam of toothed whales contains several signal components and to accurately detect and localize the components in the time-frequency domain is essential to understand to what extent the signal can be controlled by the animal and what functions it serves. This project aims to studying and characterizing multiple-channel sonar beam measurements and also possibly develop and tailor the method using information from the multiple-channel structure.
    Prerequisites: FMSF10/MASC04, (FMSN35/MASM26)

  • Long description:

    Transient signals are by nature difficult to characterize. The sonar beam of toothed whales contains several signal components and to accurately detect and localize the components in the time-frequency domain is essential to understand to what extent the signal can be controlled by the animal and what functions it serves. The scaled reassigned spectrogram estimates the time- and frequency centers of individual signals and is therefore well suited for detection and localization of transient signal components, also when they are closely located in the time-frequeny domain. This project aims to studying and characterizing multiple-channel sonar beam measurements and also possibly develop and tailor the method using information from the multiple-channel structure.
