摘　　要：VOR作用距离的试飞结果受试验区电波传播衰减影响很大，需要对其进行精确计算，为分析试飞结果提供支持。Fock级数法是计算电波衰减的一种精确方法，本文详细讨论了应用该方法求解试验区电波传播衰减的工程计算问题。The radio propagation loss over earth＇s surface in the test region would greatly influence on the flight test results for the coverage of VOR, and need be computed accurately to support the flight test results. In this paper, the accurate Fock＇ series solution is detailed and used to calculate the propagation loss factor in a test region.

关 键 词：VOR作用距离 Fock级数法 AIRY函数
