The invention discloses an evaluation scheme for the stability of a track speed under the condition of no true value, and relates to the field of multi-target track processing. According to the invention, after the target tracking and multi-source information fusion in the field, the invention discloses a target speed stability quantitative evaluation scheme under the condition that there is no need of the real speed of a target. The scheme takes a physical motion law of the target as the reference, and the technical scheme for quantitatively evaluating the speed stability of the target and tracking the processing effect d under the condition of no true value is proposed, thereby avoiding the dependence on a speed true value or the subjectivity of human's evaluation.
