PROBLEM TO BE SOLVED: To provide an evaluation method of a target motion analysis in which the speed trap is not predicted by a commercially available radar receiver. SOLUTION: When an actual velocity is unknown, a distance in which a ratio of change of a velocity error vector (analysis evaluation point) is obtained for each measurement direction on the basis of the object measurement starting point direction using the characteristics of the velocity error vector. The distance is the actual measurement distance. When the distance connecting a point at the intersection of the measurement starting point direction with the extended line of the direction of the actual velocity vector (known), and a point at the intersection of the measurement ending point direction with the extended line of the direction of the actual velocity vector (known) is divided by the measurement time, the actual velocity is determined.
