N2 - The method proposed in this paper extracts the location information of the scattering center (SC) through in-depth analysis of the structure of the near-field target; it determines the amplitude information of the scattering center based on time-frequency feature, and models the near-field scattering center based on the high-frequency analytical expression of the near-field scattering feature.Taking a certain type of missile target as an example, the accuracy of this method was verified by comparing with the results of multilevel fast multipole algorithm(PMLFMA). The modeling method in this article can provide certain reference significance for research in the fields of radar target identification, tracking and positioning.
