蒸发波导模型概述

Overview of Evaporation Duct Models

蒸发波导是在海上低空环境中发生概率最高的一种大气波导,可有效利用蒸发波导传播条件使雷达实现远距离目标探测。本文分析了海上大气波导的形成条件,阐述了蒸发波导模型提出的重要意义。综述了几种典型的蒸发波导模型研究应用状况。最后,展望了未来的研究工作方向。

Evaporation duct is an atmospheric duct with the highest probability of occurrence in maritime and low latitude environment.It can effectively use the evaporation duct propagation conditions to enable radar to achieve long-distance target detection.This paper analyzes the formation conditions of atmospheric ducts over the sea and elaborates the significance of the evaporation duct model.The application of several typical evaporation duct models is reviewed.Finally,future research direction is prospected.
