<p><P>PROBLEM TO BE SOLVED: To provide a radar apparatus having a high target discrimination ability capable of discriminating between a target in the same lane as one's own vehicle and a target in an adjacent lane even while travelling in a curved road. <P>SOLUTION: A signal processing means 8 acquires the amount of locational deviation between an object (target) 1 and one's own vehicle in the directions to the right and left of one's own vehicle. At this time, a correction operator 19 corrects the amount of locational deviation while one's own vehicle is traveling in a curved lane into the amount of locational deviation of the case that a lane is in a rectilinear road. A correction operator 19 acquires the turning radius R of one's own vehicle traveling in the curved lane and the distance R' between the center of rotation of one's own vehicle and the object, and takes the difference between the turning radius R and the distance R' as the amount of locational variation after the correction. It is possible to compute the turning radius R through the use of acceleration in the forward and backward directions of one's own vehicle and in the directions to the right and left. <P>COPYRIGHT: (C)2004,JPO</p> |
