The invention relates to an
ionosphere hybrid modeling method in a short-wave
ray tracing technique. The method comprises the following eight steps conducted through an input module, an IRI module, a QPS module and a
ray tracing module: 1. inputting initial parameters such as testing time, working frequency,
transmitter coordinates,
receiver coordinates, antenna elevation range and the like; 2. figuring out reflection midpoint position, geocentric angle, great-circle distance and
azimuth angle according to the
transmitter coordinates and the
receiver coordinates; 3. calculating the relevant parameters of an E layer and an F2 layer at a radio reflection midpoint at the testing time by using IRI model
software; 4. transmitting the parameters of each layer figured out by an IRI model to a QPS model and using the parameters as input parameters to establish the multilayer quasi-parabolic
plasma frequency distribution of a reflection space; 5. using the multilayer quasi-parabolic
plasma frequency distribution of the reflection space and taking a group path as an independent variable to gradually solve a
ray tracing equations set by starting from the
transmitter position to obtain a group path
simulation value of radio
waves from the transmitter to the
receiver; 6. conducting ray tracing calculation under the IRI model
plasma frequency distribution to obtain a
radio wave group path
simulation value under the IRI model; 7. conducting a test to obtain an actually measured
radio wave group path; and 8. comparing the
simulation value with the actually measured value to verify the validity of the
hybrid modeling method.
