Abstract

In this paper, radar cross section (RCS) analysis program, RACSAN has been developed to predict RCS of complex structures. RACSAN is based on the high frequency range analysis method of Kirchhoff approximation in physical optics (PO). This program can present RCS including multi-bounce effect in complex structures by combination of geometric optics (GO) and PO method. GO method has a concern in the evaluation of the effective area, and PO method is involved in the calculation of RCS for the final effective area that is evaluated by GO method. Comparisons of the predicted results and analytical solutions showed that the developed program could be an effective tool for predicting RCS in complex structures.

본 연구에서는 복합 구조물의 레이더 반사면적을 해석하기 위한 프로그램 RACSAN을 개발하였다. 본 프로그램은 물리 광학을 기초로 한 고주파 대역에서의 키르히호프 근사법을 기반으로 하고 있다. 또한, 본 프로그램은 물리/기하 광학 혼합방법을 이용하여 복합 구조물의 다중 반사 효과를 고려 할 수 있다. 즉, 기하 광학을 이용하여 다중 반사 시 유효면적을 계산하고 최종 반사면에서는 물리광학을 이용하여 레이더 반사면적을 해석한다. 개발된 프로그램의 신뢰성 확보를 위하여 이론해가 있는 구조물들의 결과들과 비교하여 본 프로그램이 복합 구조물의 레이더 반사면적 해석에 유용하게 사용될 수 있는 것을 확인하였다.
