Abstract :
It is shown that the radar cross section (RCS) of complex targets can be obtained in real time using the hardware capabilities of a high-performance graphics workstation. Target geometry is modeled by a computer-aided-design package. The RCS is computed using the physical-optics high-frequency approximation. In order to validate the graphic processing of the surface integral, the results obtained for simple objects are compared with analytic evaluation of the physical-optics integral. A generic missile model is used to validate the physical-optics results for complex radar targets at high frequency. It is found that the RCS of complex targets at high frequency is predicted with reasonable accuracy by the physical-optics approximation.<>
