다 대역 영상레이다장비의 유령영상 위치 = Positions of Ghost Images on Multiband Synthetic Aperture Radar

다국어 초록 (Multilingual Abstract)

In deramped synthetic aperture radar (SAR) equipment that utilizes two or more different bands (different center frequencies), if different pulse repetition frequencies (PRFs) are employed when using a single receiver, owing to its economic feasibility, images of other bands may appear and become ghost images. In this study, to determine the exact location of a ghost image illustrated in inverse SAR images, mathematical formulas are adopted to determine the location of the ghost image in the multiband. Even if the bandwidth and PRF are the same, if Tu (unprocessed time interval) is different, we can observe that a ghost image appears near the actual image.
If a time delay is noted, the ghost image appears at the same position as that in the absence of a delay. Thus, the effect of ghost images should be minimized by changing Tu.
