    摘要: 【課題】検出物体との相対速度が0である場合であっても、検出物体が走行中であるか否かを判断する 【解決手段】レーダ装置4は、複数の観測点について、観測点相対速度に関連する相対速度パラメータと、観測点で反射したレーダ波の反射強度に関連する反射強度パラメータとの対応関係を示す強度分布を作成する。さらにレーダ装置4は、反射強度のピークに対応する相対速度パラメータである中心相対速度パラメータから相対速度パラメータが大きくなるほど反射強度パラメータが小さくなり、且つ、中心相対速度パラメータから相対速度パラメータが小さくなるほど反射強度パラメータが小さくなり、且つ、反射強度パラメータの分布が中心相対速度パラメータを中心として対称である場合に、走行車両を検出したと判断する。 【選択図】図1

    摘要: PROBLEM TO BE SOLVED: To provide a technique for preventing a radar device from erroneously determining different pieces of object information as a single object.
    SOLUTION: A detection point second-closest to the vehicle next to a representative detection point detected in a first scanning is set as a representative detection point in a second scanning when the representative detection point in the first scanning is not present in the second scanning. It is determined that the first representative detection point and the second representative detection point are information of different objects when the second representative detection point exists at a position distant from a position of the representative detection point in the first scanning by equal to or more than a predetermined distance. Accordingly, erroneous determination of the movement direction of an object caused by determining different pieces of object information as a single object is prevented.

    摘要: 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.

    摘要: PROBLEM TO BE SOLVED: To provide an inexpensive radar system capable of determining precisely a kind of an object, using a monopulse type radar for executing wide angle two-dimensional monitoring.
    SOLUTION: Reflected waves in a plurality of portions on the object moving within a monitoring area are received using the radar system adopting a monopulse type for measuring an angle, to measure the reflection portion as to the each reflected wave. A position of the moving object and a size thereof in an angle measuring direction of the monitoring radar system are calculated, based on a measured data.
