| Abstract: | The real-time acoustic signal acquisition and discrimination technology of marine mammals(such as cetaceans and dolphins)is of great significance for ocean scientific research and marine ecological protection in China′s coastal waters.In this paper,a real-time data acquisition and analysis system of whale and dolphin sound signal based on FPGA is designed.The hardware of the system takes FPGA as the core.While collecting and storing the sound signal in the aquarium,the improved HHT algorithm is applied to process the click signal of whale and dolphin calls to realize the real-time identification of bottlenose dolphins and beluga whales,which can be used for real-time Ocean Tracking scientific research of large mammals. |
