| Abstract: | Results of Data-Link operation range obtained from flight test is greatly influenced by radio propagation over earth's surface in the test region.As a means of results analysis,the singal's propagation loss along a given path must be accurately predicted according to a mathematical model.In this paper,the Fock'series solution which is an accurate method applied to this problem is employed.An algorithm for computing the propagation factor on the basis of Fock'series solution is presented in detail. |
