PROBLEM TO BE SOLVED: To detect only a target at a high detection rate.SOLUTION: A reference cell extraction part 110 selects a target cell 101a from a radar image 191 and extracts a reference cell 101b from the radar image 191. A pixel average value calculation part 120 calculates a pixel average value 102 of the reference cell 101b. A pixel standard deviation calculation part 130 calculates a pixel standard deviation 103 of the reference cell 101b. A standard deviation correction value calculation part 140 calculates a difference between the pixel average value 102 and the pixel standard deviation 103 as a standard deviation correction value 104, and a target detection image generation part 141 sets the standard deviation correction value 104 in a pixel area of the target detection image 194 corresponding to the target cell 101a. A target detection part 150 specifies a pixel area larger than a detection threshold as a target area from the target detection image 194 and calculates a coordinate value corresponding to the specified target area as a target coordinate value 195.
