In order to solve the problem that the dynamic measurement of non-cooperative targets was difficult to carry out, the real-time simulation method for dynamic polarization scattering characteristics of moving target was studied in this paper. Firstly, the formulas to calculate the azimuth and elevation angles of the line of sight of radar in the target body coordinate system were derived. Secondly, the polarized scattering model of a single scattering point is introduced. Lastly, the implementation steps for eliminating obstructed points are given. The simulation results showed that the dynamic polarization scattering characteristics of moving targets are sensitive to the line of sight of radar. The validity and accuracy of the real-time simulation method were verified.
