Abstract: The present disclosure provides a method and an apparatus for quickly and accurately evaluating a trajectory of a projectile such as a satellite launching rocket or a missile by comparing the trajectory with a reference trajectory. The trajectory evaluation method includes: acquiring time series positioning data for a target and predetermined reference trajectory information; and mapping points representing the time series positioning data on a graph into corresponding points on a reference trajectory representing the predetermined reference trajectory information while relocating each mapped point onto a relocatable section taking into account a movable range dependent on a speed of the target, and determining a maximum value of distances moved by the points while the points are mapped and relocated as a similarity between the time series positioning data and the reference trajectory.
