Abstract: 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.

Abstract: A dielectric resonator antenna includes a dielectric material block extending in a first direction, a second direction different from the first direction, and a third direction perpendicular to the first direction and the second direction; and a feeding part extending in the third direction from a bottom surface of the dielectric material block to a part of the dielectric material block, wherein the feeding part overlaps a diagonal, or an extension line of the diagonal, of the bottom surface of the dielectric material block intersecting a first position where a first edge of the bottom surface of the dielectric material block parallel to the first direction and a second edge of the bottom surface of the dielectric material block parallel to the second direction meet.

Abstract: A method for detecting a moving target through a vehicle radar system includes acquiring radar data from a radar sensor disposed with respect to a vehicle, and using the radar data to detect a plane of a structure. The method also includes setting a reference classification line based on the detected plane, and determining whether the moving target is in a line of sight (LOS) area or a non-line of sight (NLOS) area based on the reference classification line.
