Study on Far-Field Scatter of Ship Wake for Micro-Bubbles Based on CST
Reliable predictions of ship wakes scattering strength are required for laser radar modeling. In this paper, far-field light scatter of wake bubbles is firstly simulated by CST software and used linearly polarized light at a frequency of 563THz (wavelength 532nm,blue light) as probe light; Analyzed the far-filed radar cross section performance of effect factors such like bubbles radius, absorption coefficient in sea water with the method of finite integral of CST. The experiment result shows scatter strength and depolarization characteristics are great variable on conditions of forward and backward scattering, and affected by the bubble radius and seawater absorption coefficient as well, this method all directions of the scatter strength and depolarization characteristics that also can be get in figures. These results provides important basis for subsequent research.
