This paper gives an analysis of the dynamic characteristics of situation elements (SEs) in situation awareness (SA) research. The purpose of the discussion is to understand the factors that influence SA and to help in designing the training systems to improve operators' SA. The status function of SEs is defined and the derivative of the function represents trends of the status of SEs at each moment. Then, Fourier transform (FT) is used to give the frequency-domain function in terms of the time-domain status function. In frequency domain, the bandwidth of the status function is used as a criterion to characterize the notion of "fast" and "slow" of the change of SE's status, which represents the dynamic characteristic of SEs. The criterion constitutes the first analytical measurement of the dynamic characteristic of SEs, which is one of the important factors that influence the SA process.
