Abstract

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.

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.
