Abstract We propose a new model of distinct thin circular disc shells to analyse the radio map of the supernova remnant (SNR) G16.2-2.7 from NRAO VLA Sky Survey at 1.4 GHz and the radio sources around it. It is obtained that the 20 radio sources around the SNR G16.2-2.7 distribute on the four thin circular disc shells. The results support the shell-like structure strongly and further indicate that the shell-like structure is several thin circular disc shells. Because the shell-like structure dominate the total sample, our results is important for the research of radio mophology of SNRs.
