The high frequency ionospheric sounding system developed by the Ionospheric Laboratory of Wuhan University is a monostatic radio system,transmitting long coded pulse train for the high pulse compressing gain and receiving the echoes during the interpulse period.The frequency standard with high accuracy and the GPS receiver are installed in the system for the frequency and time synchronization.Now the monostatic system can be used for the monostatic oblique backscatter detection and the vertical-incidence detection;two systems can be used for the bistatic oblique backscatter detection and the oblique-incidence detection.The monostatic and bistatic oblique backscatter ionogram,oblique ionogram and vertical ionogram with high quality were well recorded in several experiments. 电离层斜向返回探测 电离层斜测 电离层垂测 多普勒测量 ionospheric oblique backscatter detection ionospheric oblique-incident detection ionospheric vertical-incident detection Doppler measurement 10.14188/j.1671-8836.2011.02.005 TH76 国家自然科学基金资助项目（40804042,41074115）;武汉大学自主科研项目（4081004） 2011-02-01 2021-04-01 2 57
