1. A method for detecting a moving target through a vehicle radar system, comprising:
acquiring radar data from a radar sensor disposed with respect to a vehicle;
using the radar data to detect at least one plane of at least one structure;
setting at least one reference classification line based on the at least one plane of the at least one structure; 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 at least one reference classification line,
wherein the at least one reference classification line is set based on a traveling direction of the vehicle,
wherein the determining comprises:
determining that the moving target is in the NLOS area when the radar data for the moving target is positioned beyond a predetermined distance from the vehicle based on the at least one reference classification line, and
determining that the moving target is in the LOS area when the radar data for the moving target is positioned within a predetermined distance of the vehicle based on the at least one reference classification line.
