NOISE TONE ELIMINATION METHOD IN DIGITAL AREA FOR SYNTHETIC APERTURE RADAR RECEIVER, SYNTHETIC APERTURE RADAR RECEIVER AND COMPUTER READABLE RECORD-MIDIUM ON WHICH PROGRAM FOR EXCUTING METHOD THEREOF

摘要

The present invention relates to a method to remove a noise tone in a digital area of a synthetic aperture radar receiver, a synthetic aperture radar receiver and a computer-readable recording medium for the same. A method to remove a noise tone in a digital domain of a synthetic aperture radar receiver using a deramping structure according to an embodiment of the present invention comprises: (a) a step of extracting a noise tone location of a deramped image signal; (b) a step of selecting a noise tone of the noise tone extracted by step (a) to be removed; and (c) a step of removing the noise tone selected by the (b) step from raw data.
