Abstract:

Based on the field strength simulation calculation and maximum usable frequency (MUF) prediction on the short-wave (HF) when propagating through ionosphere E or F2, selections of deployment position, operation time and emission frequency for the vehicle mobile HF transmitter to obtain the maximum field strength at the scheduled receiving spot are proposed when considering the reflection of HF by ionosphere E or F2. Rationality of the simulation model is proved through the comparison between software simulation prediction and test data, which will provide more reasonable assistant decision-making suggestion for the deployment scheme of HF transmitter.
