<p>PROBLEM TO BE SOLVED: To provide a synthetic aperture radar device configured to form a wide-range image even when there is a constraint on processing scale.SOLUTION: A synthetic aperture radar device is configured to form an image by applying synthetic aperture processing on a beam output obtained by directing a radar wave to a specific imaging range as a moving body moves. A focal position is changed in M (M is a natural number of 2 or more) patterns for each of N (N is a natural number of 2 or more) patterns of center positions, for an area to be imaged, to generate a reference signal in each range-cross range axis. A plurality of SAR images are generated by applying SAR processing by matching between each of obtained data of the beam output and the reference signals. Misalignment between the SAR images is corrected. The SAR images with corrected misalignment are integrated to form a SAR integrated image.</p> |
