초록

본 연구는 축소형 항공기의 레이다 단면적 분석 및 측정에 대한 연구이다. 사전에 축소형 항공기에 대한 레이다 단면적 특성을 전자기 해석 툴을 사용하여 분석하고 실제 축소형 항공기를 제작하여 무반사실에서 측정하였다. 측정 시 구모델을 사용하여 RCS 특성의 기준 데이터로 적용하여 실제 축소형 모델의 시험 결과 데이터에 적용하였다. 측정 방법은 시간 게이팅을 적용하여 무반사실 내부에서 산란되는 성분에 대한 영향을 제거하여 측정의 정확성을 향상시켰다. 축소형 모델의 RCS 시험 결과는 사전 해석 결과와 같이 초단파 대역에서 상대적으로 RCS 특성이 높게 측정되었다. 향후 본 연구를 통하여 파장이 상대적으로 큰 VHF/UHF 대역 레이다의 표적에 대한 RCS 분석 및 측정에 대한 특성 기술에 활용할 예정이다.

This study is a study on the analysis and measurement of the radar cross-sectional area of a miniature aircraft. Radar cross-sectional area for miniature aircraft in advance were analyzed using an electromagnetic analysis tool, and an actual miniature aircraft was manufactured and measured in an anechoic chamber. When measuring, the old model was used as reference data for RCS(radar cross section) characteristics and applied to the test result data of the actual reduced model. The measurement method improved the accuracy of the measurement by applying time gating to remove the influence on the components scattered inside the anechoic chamber. The RCS test results of the reduced model showed relatively high RCS characteristics in the microwave band, as the previous analysis results. In the future, we plan to utilize the method of RCS analysis and measurement for the target of the radar in the VHF(Very High Frequency)/UHF(Ultra High Frequency) band with a relatively large wavelength.
