abstract = {The lack of data is constraining research on the bistatic ballistic target (BT). In the bistatic radar system, the angle between the target axis and the radar line of sight (RLOS) is generally large, which means that the specular scattering center (SSC) is likely to be present with the target’s micro-motion. This results in a brief flash in the time-frequency representation (TFR) but has been less frequently reported. We propose a micro-motion echo simulation method with SSC by calculating its position vector and modeling its visible coefficient. Furthermore, the model with four estimated parameters is utilized to optimize the simulated TFR. The simulation results intuitively and numerically agree well with the TFR obtained by electromagnetic calculation.}
