Abstract: Herein, the technical characteristics and programme of Qujing incoherent scatter radar (the first one in China Mainland) are described. The measurement ability in the ionosphere, space debris, and the Moon was investigated using the data. The results showed that this radar is of importance useful for the measuring ionospheric climatologic property, analyzing storm-time and abnormal enhancement events analysis, studying E-F valley and its variations, the determining and modeling space debris distribution characteristics and model, and identifying the scatter echo characteristics from the different regions of the Moon. The next work will focus on the measurement of the structure and evolution of the lower ionosphere and the northern ionosphere crest, storm-time variations, and disturbance characteristics property.
