Analysis of Time-Domain Scattering Characteristics of Large Marine Ships Based on closed-form TDSBR

摘要

In this paper, the TDSBR method based on analytical closed-form integral is used to calculate the time-domain scattering characteristics of large ships at sea. The method can use larger patches to establish a calculation model, which significantly reduce the amount of calculation of the intersection of the rays and planes. The two-dimensional imaging method clearly shows the process of the target being gradually "illuminated" by the incident pulse over time. The method is proved to be fast in calculation and high in accuracy, and is suitable for analysis of scattering characteristics of electric power targets.
