摘要：
Based on the ionospheric quasi-parabolic model, the travelling ionospheric disturbance (TID) induced by the atmospheric gravity waves is modeled analytically and quantitatively. A versatile 3D ray tracing technique is applied into the TID model for analyzing the effect of TID on the skywave over-the-horizon radar coordinate registration (CR). The numerical results indicate that the effect of small scale TID is negligible, the effect of medium scale TID on CR is considerable, and the large scale TID is capable of changing the normal CR relation significantly and vitiates the CR accuracy. It can also be concluded that the azimuth transformation is affected by the TID slightly.
