非视线紫外光大气传输模型的建立及验证

基于蒙特卡罗方法建立了非视线紫外光传输模型。利用此模型模拟了不同传输距离、不同发射和接收仰角等多种传输条件下的传输情况,并在同等条件下进行了相关实验。结果表明,在相同条件下,信号强度模拟曲线与实验曲线的变化趋势相同且吻合较好,但具有一定的误差。进一步分析指出,模型中大气散射系数、吸收系数、分子散射比、传输测试距离等参数的误差影响了模拟结果的准确,以及模拟与实验曲线的吻合程度。

Establishment of non-line-of-sight ultraviolet propagation model and its experimental verification

Based on Monte-Carlo method,the non-line-of-sight ultraviolet propagation model is established.By using the model,these conditions of different transmission distances,emitting apex angles and receiver apex angles are simulated,and corresponding experiments are been taken.Result shows that there have the same tend between the curves of simulation signal intensity and the experiment. And the two curves approach each other,besides with errors.Further analysis indicates that,the errors of important parameters l...
