1. An apparatus for detecting a target using a radar, the apparatus comprising:
a first radar which is a multi-channel radar including a plurality of transmitting antennas and a plurality of receiving antennas and outputs first position information and first velocity information of a target;
a second radar which is a multi-channel radar including a plurality of transmitting antennas and a plurality of receiving antennas, is installed to be spaced apart from the first radar, and outputs second position information and second velocity information of the target;
a memory; and
a processor which is configured, when executing program instructions stored in the memory, to perform:
a position information combination operation to calculate combined position information of the target from the first position information and the second position information; and
a velocity vector information calculation operation to calculate velocity vector information of the target from the first velocity information and the second velocity information,
wherein the first radar and the second radar are installed to be spaced apart from each other such that a surface on which the first radar is installed and a surface on which the second radar is installed form an inclination angle, and
wherein the position information combination operation rotates and transforms the second position information acquired through the second radar by the inclination angle and shifts and transforms the second position information vertically and horizontally by the distance difference between the centers of the first and second radars, and then combines the second position information with the first position information.
