2010年年初，國立中央大學於花蓮東華大學架設台灣第二代動態式電離層探測儀，第一代動態式電離層探測儀為70年代晚期美國國家海洋暨大氣局(National Oceanic and Atmospheric Administration, NOAA)之高頻雷達，採類比收發機設計。新一代的收發機配合現今的數位科技，利用數位收發機技術，設計了第二代動態式電離層探測儀。論文中分別介紹雷達系統硬體與軟體部分，由於其軟體原始碼都是開放的，因此使用者可以依照自己的分析軟體進行資料處理。此套雷達系統不僅可用來做電離層研究，其被動模式也可用來監測臺灣東部地區背景環境噪音，找出適當的頻率來做中高頻通訊傳播。A new dynasonde in second generation has been established by National Central University at Dong-Hwa University in Hualien, Taiwan since the beginning of 2010. The first-generation dynasonde which is an analog transceiver was built by National Oceanic and Atmospheric Administration (NOAA) in the late 1970’s. The second-generation dynasonde was developed by taking the advantage of the digital technology today and utilizing the technique of digital transceiver. In this study, we introduce hardware and software of the system separately. Because of the open source software, users can develop their own analysis software to process the data. Not only does the radar system benefit the ionospheric research, but it also helps to survey the radio frequency interferences in order to study the appropriate bands for MF/HF communication in eastern Taiwan.
