PROBLEM TO BE SOLVED: To provide an image radar device capable of performing fluctuation compensation without specifying a parameter of interpolation on observation data.SOLUTION: An upsampling rate calculation part 10b calculates an upsampling rate of observation data within respective determination allowable values of resolution in a range direction, resolution in an azimuth direction and a signal-to-noise power ratio, determining picture quality when the observation data is imaged, from the respective deterioration allowable values and various elements of a radar. An observation data upsampling part 10c upsamples observation data having its phase compensated by a phase compensation part 10a based upon the upsampling rate that the upsampling rate calculation part 10b calculates. A nearest neighbour interpolation part 10d performs nearest neighbour interpolation on the observation data that the observation data upsampling part 10c upsamples based upon a difference based upon the difference between a measured movement track of the radar and a linear track obtained by approximating it to a straight line.SELECTED DRAWING: Figure 1 |
