| 摘 要： | 主要研究利用GPS掩星观测得到的大气垂直折射率分布梯度来计算考虑大气折射情况下的地球等效半径,从而根据雷达探测距离公式对雷达探测范围进行预计。从GPS掩星结果与雷达探测距离公式的联系入手,从原理上介绍了所提出方法的思路,并阐述了方法的可行性。

| Abstract: | The main work of this paper is calculating the detection range of naval radar with the equivalent earth radius which is derived from vertical atmospheric refractivity profile that is figured out from GPS occultation data.Based on the relationship between GPS occultation data and the calculating formula of radar detection range,the author expounds the logicality and feasibility of this method in principle. |
