Radar Cross Section (RCS) is
one of the most considerable parameters for ship stealth design. As modern
ships are larger than their predecessors, RCS must be managed at each design
stage for its reduction. For predicting RCS of ship, Radar Cross Section Analysis
Program (RACSAN) based on Kirchhoff approximation in high frequency range has
been developed. This program can present RCS including multi-bounce effect in
exterior and interior structure by combination of geometric optics (GO) and
physical optics (PO) methods, coating effect by using Fresnel reflection
coefficient, and response time pattern for detected target. In this paper, RCS
calculations of ship model with above effects are simulated by using this
developed program and RCS results are discussed.？
