Title:
FM-CWレーダの路上静止物検知方法
Document Type and Number:
Japanese Patent JP4698048
Kind Code:
B2
Abstract:
A method capable of determining whether a target detected by a radar is a stationary on-road object or not is disclosed, wherein a fluctuation in the reception level of a reflected wave from a target is obtained in relation to the distance of the target, a difference in reception level between a maximum point and a minimum point is obtained from the fluctuation of the reception level, and when the obtained difference is larger than a predetermined threshold value, it is determined that the target is a stationary on-road object. Further, slope over the distance between the maximum point and the minimum point is obtained, and when the obtained slope is greater than a predetermined threshold value, it is determined that the target is a stationary on-road object. Further, the distance between maximum points or between minimum points is obtained, and when the obtained distance is smaller than a predetermined threshold value, it is determined that the target is a stationary on-road object.
