Disclosed is an apparatus for tracking an object based on radar image reconstruction, the apparatus including a two-dimensional image producing unit configured to produce a two-dimensional image by collecting multiple one-dimensional radar signals from which clutter is removed, an object detecting unit configured to determine the presence or absence of an object from the two-dimensional image and estimate a two-dimensional position of the present object, and an object tracking unit configured to track a movement path of the object based on the two-dimensional position estimated by the object detecting unit.
