| 摘 要： | 在米氏散射理论的基础上,通过仿真试验分析了不同浓度的雾对水面舰船目标偏振特性的影响,并利用6SV模型对其进行了数值模拟,得到了雾对目标偏振特性的影响数据。随着雾的浓度的不断增加,退偏现象趋于明显。然后对产生退偏现象的原因进行了分析。该试验结果对于偏振探测技术在雾天环境下的应用具有一定的参考价值。

| Abstract: | On the basis of Mie scattering theory, the effect of fog with different concentration on the polarization characteristics of a surface ship target is analyzed in a simulation experiment. By carrying out numerical simulation with a 6SV model, the data about the effect of fog on target polarization characteristics is obtained. It is found that with the increase of fog concentration, the depolarization phenomenon is getting more obvious. The reason of this depolarization phenomenon is analyzed. The result is of reference value to the application of polarization detection technologies in fog environment. |
