APPARATUS AND METHOD FOR GENERATING IDENTIFICATION SIGNAL OF TRAFFIC LANE USING RADAR, APPARATUS AND METHOD FOR TRAFFIC LANE IDENTIFICATION OF RECEIVED SIGNAL USING RADAR

摘要

The present invention relates to an apparatus and a method for generating lane identification signals for identifying signals reflected by a road for respective lanes, and an apparatus and a method for lane identification. When generating a lane signal, a resolution coefficient corresponding to a lane width based on a predetermined parameter for road circumstances is calculated, an M-SEQ synchronization frequency for generating an M-SEQ signal, which is a lane identification signal, is generated based on a predetermined frequency signal and the resolution coefficient, and an M-SEQ signal is generated based on the M-SEQ synchronization frequency. Further, when identifying signals reflected by a road for respective lanes, an M-REF signal is generated which is a reference signal of the M-SEQ signal generated based on the resolution coefficient corresponding to a lane width calculated based on a predetermined parameter for road circumstances, and the received signal is identified for respective lanes by being compared with the M-REF signal. Therefore, a lane identification signal having a radar resolution corresponding to various land widths can be precisely generated, and lane identification signals can be accorded with a road such that lanes can be precisely identified regardless of whether a road shoulder or a median strip exists or not, the widths of the road shoulder or the median strip, or the various widths of the lanes. In addition, since the received signals can be precisely identified for respective lanes, a traffic control of a multi-lane road can be effectively performed.
