| Abstract: | A new propagation mode is composed of the ionosphere reflection propagation mode and the surface-wave propagation mode. The new mode construct, path loss factors, Doppler spectral characteristics and working frequency characteristics as well as the possible application of the new mode were investigated. For the new mode applied to the OTHR of sky-and-Surface wave association system, the radar equation, the orientation equation and the information processing model were derived. The simulation examples indicated that the radar system is of wonderful feasibilities. |
