Abstract: China Dual Auroral Radar Network (CN-DARN) has established three stations and six high-frequency coherent scatter radars in Siziwang, Inner Mongolia Longjing Jilin, and Hejing Xinjiang. This paper utilizes the wide-area high-precision ionospheric irregularities autonomous detection data produced by the six mid-latitude high-frequency coherent scatter radars: Siziwang East Radar (SZE), Siziwang West Radar (SZW), Longjing East Radar (LJE), Longjing West Radar (LJW), Hejing East Radar (HJE), and Hejing West Radar (HJW). According to the time line of the construction of the radar station, the observation results of each radar in the geomagnetic quiet period and geomagnetic storm period are presented in this paper. Then we compared the data of the six high-frequency radars with other international SuperDARN radars (such as Jiamusi Radar, JME; Hokkaido Radars, HOK, etc.). Further, the ionospheric convection map of the northern hemisphere was obtained by using all the SuperDARN radar data observed during the magnetic storm. The analysis results show that the plasma convection observed by six high frequency radars in the northern mid-latitude of the CN-DARN is consistent with the typical characteristics of ionospheric convection during the magnetic storm. The analysis in this paper confirms the validity of the mid-latitude HF radar data of the CN-DARN, and lays a foundation for the scientific output of the subsequent mid-latitude high frequency radar data.
