| 摘 要： | 蒸发波导是海洋大气中一种常见的自然现象,受其影响,电磁波的传播轨迹会显著改变。针对蒸发波导的探测,提出了利用岸基铁塔气象梯度仪进行蒸发波导探测法方法并进行了分析,同时与蒸发波导模型的结果进行了初步比较,表明梯度仪是蒸发波导探测的有效手段,对波导模型的修正和蒸发波导条件下雷达最大探测距离的预测具有一定的指导意义。 |

| Abstract: | Evapora tion ducts are common phenomena over the oceans,and they severely impair radio w ave systems by changing the paths of electromagnetic waves.A method for detecting the evaporation ducts using hydro m eteorological observations data from coast-based meteorological grads tower is presented,and the detection results are used for comparison with the evaporation duct model,which indicates that the meteorological grads tower is an effective means for evaporation duct detection.The conclusion offers some help for improvi ng the evaporation duct model and forecasting the maximum radar detection range under the condition of evaporation ducts. |
