武汉大学电离层实验室研制的短波电离层探测系统是一部单站雷达,发射长编码调相脉冲串信号获得高脉冲压缩增益,并在脉冲间隔期间接收回波.在系统中加入了高精度频率源和GPS接收机,以实现系统间的频率和时间同步.单台系统可用于单站斜向返回探测和垂直入射探测,两台系统配合工作可实现双站斜向返回探测和斜入射探测.经多次实验得到了高质量的单站和双站斜返电离图、斜测电离图和垂测电离图. The shortwave ionosphere detection system developed by the ionospheric laboratory in Wuhan University is a single-station radar, which transmits long-coded phase-modulated burst signals to obtain high pulse compression gain and receives echoes during the pulse interval. A high-precision Frequency source and GPS receiver to achieve frequency and time synchronization between systems Single system for single-station oblique return detection and vertical incidence detection, two systems work together to achieve double-station oblique return detection and oblique incidence detection After repeated experiments, high quality single station and double station oblique back ionization maps, oblique ionization maps and vertical ionization maps were obtained.
