The Propagation Delay Analysis of Short-wave Multipath Based on the Ionospheric Ray-tracing Homing-in Algorithm

To investigate the propagation delay of short-wave multipath on a fixed transceiver link, based on the International Reference Ionosphere and International Geomagnetic Reference Field models, this paper realizes point-to-point ray tracing homing-in by combining the ray-tracing method and homing-in algorithm. Taking the Nanjing-Chongqing communication link as an example, the propagation delays of multipath reflected in the same layer are numerically simulated and compared. The results show multipath delay induced by multi-hop is more significant than that induced by ionospheric dispersion.
