High-Frequency Channel Modeling Based on the Multi-Source Ionospheric Assimilation Model

In this paper, we explored how to more accurately predict the quality of high-frequency links and better research improve capabilities communication, reconnaissance, positioning systems. Based on background electron density generated by ionospheric assimilation model 3D ray-tracing technology, realistic accurate channel parameters with physical meanings were obtained. On basis, a complete that can be used for simulation prediction was constructed. First, model, method calculating based multi-source are introduced. Then, HF oblique sounding experiment experimental data processing Finally, modeling compared results. The results showed proposed in paper similar average deviation difference between ones group path, path broadening, Doppler frequency shift 29.2200 km, 17.3456 0.2121 Hz, respectively. delay, shift, delay broadening calculated relatively could reporting prediction, reconnaissance geolocation, radar selection positioning, etc.
