<p><P>PROBLEM TO BE SOLVED: To obtain a radar image processing device that does not cause deterioration in resolution even for SAR data imaged under complicated track condition deviated from an ideal linear track by applying a suitable sway compensation process. <P>SOLUTION: The radar image processing device includes a fluctuation compensation amount calculation unit 1 that calculates an actual slant range change R<SB POS="POST">act</SB>of a platform and an ideal slant change R<SB POS="POST">ideal</SB>which approximates the actual slant range change, and calculates a fluctuation compensation amountϕbased on a difference between the actual slant range change R<SB POS="POST">act</SB>and the ideal slant change R<SB POS="POST">ideal</SB>; and a fluctuation compensation processing unit 2 that applies phase compensation to a receiving signal by using the fluctuation compensation amountϕcalculated by the fluctuation compensation amount calculation unit 1. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
