| 摘 要： | 在薄层散射的基础上，研究了寻常散射和非常散射的差别，建立起了散射椭圆的模型。然后从薄层散射过渡到厚层散射，检测了激光在水中的散射场和退偏振度，并对前向散射和后向散射导出了简化的场强计算公式：公式中的常数一散射率成为评价激光散射场和退偏振的依据。本研究的结论直接对提高水中目标探测的信噪比有现实意义。

| Abstract: | Based on water thin-layer scattering, the difference between the ordinary scattering and the extraordinary scattering is studied, setting up the model of scattering ellipse. Through the transition from water thin-layer scattering to thick-layer scattering, scattering field and depolarizability of laser in water are tested, and simplified field strength formulas for forward and backward scatterings are derived. The constant in the formulas-scattered power is regarded as basis for the evaluation of scattering field and depolarizability. |
