- Abstract:
- We analyzed the data of four airgun experiments in different water shapes to obtain the influence relation-ship of different water shapes on wavefrom of airgun and carried out corresponding numerical simulations to simulate the process of airgun exciting in different water shapes.We find that water shape has an influence on airgun triggered signals.The influence on high frequency is strong but on low frequency is weak.Among our four experiments,the MPQ Pool experiment has highest energy transform efficiency and a sharp waveform.
