Abstract: For distributed high-frequency radar system and short-wave time difference of arrival location methods, the consistency and coherence of characteristic parameters of the adjacent ionospheric short-wave channels need to be considered as key factors. In this paper, a multi-station short-wave ionospheric channel oblique sounding experiment with synchronous networking is carried out preliminarily in Wuhan, Daofu, Leshan by employing the equipments with independent intellectual property. The results show that, when the sun and geomagnetic activity are calm, for the two similar links of Wuhan-Daofu and Wuhan-Leshan, the statistical characteristics of the channel parameters such as the diurnal variation of channel group delay, group delay broadening, Doppler shift and Doppler broadening are basically equal. The signals received by Daofu and Leshan from Wuhan can still get obvious correlation peaks after being propagated through the ionosphere. Meanwhile, they have the linear phase change laws and a stable phase difference. In this paper, it is proved that the adjacent short-wave ionospheric channels have good parameter consistency and coherence over a short distance range.
