IPC: G01S13/87
Filed: 2019-08-07
Abstract: To detect a target by suppressing a virtual image without overlooking the real target even if the virtual image overlaps with the real target.SOLUTION: In a target detection device 1, first and second targets are detected by a millimeter wave radar 10 having a small visual field angle and a wide-angle sensor 20 having a large visual field angle, respectively. Detection information includes the targets' positions and feature information, and a detection likelihood ratio. A target analysis part 30 outputs an existence probability for showing in which position a target actually exists. Therefore, an identical target determination part 102 compares the position and feature information of the first target with the position and feature information of the second target to determine whether the first and second targets are identical targets. When the determination result shows that the first target is estimated to be a virtual image of the second target, a likelihood ratio correction computation part 103 corrects a detection likelihood ratio of the first target by using a detection likelihood ratio of the second target, and computes an existence probability that the first target actually exists.SELECTED DRAWING: Figure 1
