摘　　要：The China-Iceland joint Arctic observatory(CIAO)has formally been operating since October 18,2018,and an imaging riometer system was deployed at CIAO in August 2019 for the conjunction observation purpose with the co-located ground-based all sky imager auroral observation system.The features of the riometer and antenna system are presented.The riometer’s beam-forming performance were evaluated with the analysis method introduced in detail.The analysis results showed that the mapping of beams was incorrectly ordered,and the correction has been made.The revised ordering result was reasonably verified and the analysis method was proved to be effective.
