The susceptibility of warships denotes the hit probability by anti-ship missiles in a hostile environment. The distribution characteristics of the hit location directly influence the vulnerability. This paper proposes a simulation method to determine the hit location of radar-homing anti-ship missiles by their approach direction. The method uses high-frequency analysis theory to calculate electromagnetic scatterers and determines the equivalent scattering center position corresponding to the hit location. The proposed method was implemented to an in-house software called SCTracer/RCS, which follows the process: importing numerical analysis model, defining calculation condition, calculating electromagnetic wave scattering centers, storing to database, calling scattering center data, estimating equivalent scattering center, and analyzing hit-point distribution. To validate the feasibility and practical applicability of this software, the hit-point distribution is examined for a 90-meter-class virtual warship.
