| 摘 要： | 本文研究了海洋蒸发波导条件下如何利用船舶报数据对雷达的探测距离进行计算,通过所需海区和时间段有效的历年船舶报气象信息得到大气折射率剖面,再利用抛物型方程计算出电磁波传播单程损耗,接着利用雷达方程得到目标的传播损耗门限,最后得到所需海区和时间段的雷达对目标的最远作用距离.实测结果表明,此方法是可行的.

| Abstract: | In this paper,the way to calculate the radar detection range in the condition of oceanic evaporation duct based on the ship-report data is discussed.Getting refractive index section by using historical effective meteorological data of needed sea-area and slot is described.Electromagnetic wave propagational SP-loss is calculated by using the parabolic equation.Propagational loss threshold is obtained by radar equation.And then get radar detection range of needed sea-area and slot in the condition of evaporation duct.This method is confirmed by experimental data. |
