摘要

摘要: 结合激光雷达与海水水体产生的非弹性散射效应, 建立了海水中的布里渊散射模型, 提出了反演海水温度、盐度的方法, 并通过布里渊散射推导出计算海水温度和盐度的公式。采用波长为532 nm的激光雷达, 通过仿真计算, 深入探讨海水温度、盐度与布里渊散射的相互关系, 得到了不同深度的布里渊频移量与温度、盐度图表,从而得出海水相应深度处的温度与盐度值。仿真数据与实际结果基本一致。

Abstract: An underwater Brillouin scattering model is built by making use of the inelastic scattering effect between lidar and seawater, and an inversion method of seawater temperature and salinity is proposed. And the calculation for-mula of seawater temperature and salinity is derived via Brillouin scattering. The lidar with the wavelength of 532 nm is employed to simulate the relationship of Brillouin scattering with seawater temperature and salinity, thus the curves of frequency shift of Brillouin scattering versus seawater temperature and salinity for different depths are obtained to esti-mate the temperature and salinity at the corresponding depths. The estimated data are consistent with the experimental values.
