基于雷达海杂波与蒸发波导模型参数化的反演方法研究

Inversion Method Based on Sea Clutter and Evaporation Duct Model Parametric

在利用雷达海杂波反演蒸发波导剖面时需要假设剖面模型来构造海杂波功率分布,论文首次将整体理查森数Rib引入蒸发波导剖面模型,不同的Rib情况下求得的蒸发波导折射率剖面不同,反演的结果也会有所差异,因此新构建的蒸发波导模型可以使反演精度得到很大提高。

When using radar sea clutter to inverse the evaporation duct section,it is needed to assume sectional model to construct the sea clutter power distribution.This paper initially introduces the bulk Richardson number Ribto the evaporation duct section model.As the Ribchanges,the evaporation duct refractive index section will vary and the inversion results will also be different.Therefore,the newly constructed evaporation duct model can greatly improve the inversion accuracy.
