Disclosed is a method of detecting a moving target by a target detecting apparatus. The method includes: acquiring radar data from a radar installed in a vehicle, extracting location coordinates of a moving target from the radar data, obtaining a line of a reflective surface on which a signal of the radar is reflected using location coordinates of a fixed object, determining whether the moving target is in a Line of Sight (LOS) area of the radar or in a Non Line of Sight (NLOS) area of the radar based on the location coordinates of the moving target and the line segment of the reflective surface, and based on determining that the moving target is in an area corresponding to the NLOS area of the radar, converting the location coordinates of the moving target into actual coordinates corresponding to an actual location of the moving target.
