      Yi, Wen; Xue, Xianghui; Reid, Iain; Murphy, Damian J.; Hall, Chris; Tsutsumi, Masaki; Ning, Baiqi; Li, Guozhu; Vincent, Robert; Chen, Jinsong; Wu, Jianfei; Chen, Tingdi; Dou, Xiankang (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-06)
      The existing distribution of meteor radars located from high- to low-latitude regions provides a favorable temporal and spatial coverage for investigating the climatology of the global mesopause density. In this study, we report the climatology of the mesopause relative density estimated using multiyear observations from nine meteor radars, namely, the Davis Station (68.6∘ S, 77.9∘ E), Svalbard ...

    • Moon Imaging Technique and Experiments Based on Sanya Incoherent Scatter Radar 

      Li, Mingyuan; Yue, Xinan; Wang, Yonghui; Wang, Junyi; Ding, Feng; Vierinen, Juha; Zhang, Ning; Wang, Zhongqiu; Ning, Baiqi; Zhao, Biqiang; Zeng, Lingqi (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-13)
      This article introduces the experiment design for Moon imaging based on Sanya incoherent scatter radar (SYISR) and algorithm research in data processing. The peak power of SYISR is 2 MW. The transmitted frequency used for Moon imaging experiments is 430 MHz. We conducted Moon imaging experiments using two types of waveforms, 13-bit Barker code, and linear frequency modulation (LFM) chirp. Considering ...
