摘　　要：讨论了基于5参数法的大气折射率剖面反演技术,利用雷达海杂波携带的传播路径上的环境信息反演大气折射率剖面.通过在我国部分海区试验情况,以某天同时存在表面波导和蒸发波导为例进行验证.试验结果表明:反演值与实际测量值在有效范围内,验证了5参数法反演大气折射率剖面技术在我国海区的适应性.此方法克服了海上条件下大气折射率剖面难于测量的困难,具有实时、方便、易行的特点.The inversion of atmospheric refractivity profile from radar＇s sea clutters based on five-parameter method which were carried by radar clutters in the propagation paths was analyzed. The experiments were carried out in some Chinese sea areas, and the same time when surface of the waveguide and evaporation waveguide existed was set as an example. Experiment results show that the value of the inversion and actual measurement are in the effective range, and the inversion of atmospheric refractivity profile from the radar＇s sea clutters based on five-parameter method is applicable to Chinese sea areas, which overcomes the difficult of atmospheric refractivity profile measurement in the condition of sea area with real-time, convenient. and easy characteristics.
