| 摘 要： | 蒸发波导环境中微波雷达经常会出现超视距探测,建立雷达超视距探测效能库有利于微波超视距雷达探测效能的发挥。提出了一种计算雷达超视距探测效能的快速算法,即以蒸发波导高度、总体理查森数和海面风速为变量,先建立雷达超视距探测效能查询表,再利用查表的方法得到各种气象条件下雷达的探测效能,以此作为探测效能库的数据基础。最后将基于此算法得到的雷达探测规律与实际观测进行了比较,表明此算法是可行的。

| Abstract: | In the evaporation duct microwave radar systems often detect Over-TheHorizon(OTH) targets.The establishment of radar OTH detection performance database can make use of the OTH radar better.A fast algorithm of calculating radar detection range was presented.At first a query table of radar detection range was established by means of evaporation duct height,bulk Richardson number and wind speed of sea surface.Then the radar detection range data in all kinds of atmospheric environment were determined from this ... |
