【Abstract】 To simulate the influences of optical wake detection system parameters on echo signal, we calculated the light scattering characteristics of single bubble by Mie theory, and solved the optical thickness of a wake cross-section in different ages. Considering the application of an optical wake detection system we designed its principle of optical path, and obtained the wake echo signal under certain system parameters by numerical method according to the principle of optical path. Simulation results show that the system parameters have significant influences on echo signal. This study may provide a theoretical reference for parameters optimization of optical wake detection system.更多还原
