针对机场夜间跑道视程难以精确测量问题,提出了一种在合适距离处架设标准光源,通过人工观测出最小可发现的灯光强度,然后迭代计算出夜间跑道 视程值的新方法。相比于现有方法,新方法的精细化程度显著提高,且较好地逼近了真值,仿真实验验证了方法的可靠性。

As the exact measurement of airport road visibility range (RVR) is so difficult, a new method was proposed. A criterion lamp-house is set at proper range, and the minimum findable light intensity is manually observed, then the RVR at night is iteratively calculated. The new method is more elaborate than current ones, and its worked result is more appropriate for the true result. The reliability of the proposed method was verified by simulation experiment.
