공간 필터링은 RCS(레이더 단면적) 측정에서 원하지 않는 산란으로 인한 원하지 않는 반사를 억제하는 유용한 방법입니다. 실제로 대형 표적의 RCS 측정을 위한 원거리장 기준을 만족하는 이상적인 장을 준비하는 것은 어렵습니다. 근거리 장에서의 바이스태틱 RCS 측정에 필터링 방법을 적용하고 스캐닝 각도 범위를 변경하여 해당 방법의 타당성을 조사했습니다. 전자기 시뮬레이션은 원치 않는 산란이 있는 근거리 데이터에서 예측된 RCS 프로파일이 테스트 대상의 원거리 참조 데이터와 밀접하게 일치함을 보여줍니다. 결론적으로, 결과는 이 방법이 실제 현장 환경에서 Bistatic RCS 측정에 효과적이라는 것을 보여줍니다.

Abstract: Spatial filtering is a useful method to suppress undesired reflection from unwanted scatters in Radar Cross Section (RCS) measurements. Actually, it is difficult to prepare an ideal field which satisfies the far-field criterion for RCS measurements of large targets. We applied the filtering method to a bistatic RCS measurement in a near field and investigated the validity of that method by varying the scanning angular span. Electromagnetic simulations show that predicted RCS profiles from near-field data with unwanted scatters closely matched far-field reference data of the test target. In conclusion, the results show that the method is effective for bistatic RCS measurements in practical field enviroments.
