초록

SAR(Synthetic Aperture Radar)는 radio wave를 이용하여 영상 정보를 얻는 Radar이다. Platform이 radio wave를 방사하여, 대상 물체에서 되돌아오는 후방 산란파 (Back-scattering) 신호를 거리에 따라 2차원 영상(SAR image)으로 기록하여 지형도를 작성한다. 본 논문에서는 SAR image 복구를 위해 SAR image processing에서 다양한 window를 적용하는 시뮬레이션을 통하여 window의 적용 효과를 연구하였으며, 그 결과 신호의 SNR 측면에서는 Flattop window가 가장 좋은 성능 향상을 보여 주는 것을 확인하였다.

SAR is a Radar to obtain the video information using a radio wave. Platform emit the radio wave, depending backscattered waves returned from the target object the signal to the distance, to create a topographical map is recorded in two-dimensional image. In this paper, through a simulation to apply a variety of window in the SAR image processing for SAR image recovery is to study the application effect of the window, as a result, at the side of the signal of the SNR, Flattop window to improve the best performance it was confirmed to show.
