    • The invention provides a method for analyzing reflection signals. Reflection signals corresponding to reflection point candidates (RPC1, RPC2, RPC3) are received (S1) by a sensor (S). For first to third reflection signals corresponding to respective first to third reflection point candidates (RPC1, RPC2, RPC3), distances (d1, d2, d3, x1, x2) are determined (S2). A first distance (d1) extends between the first and second reflection point candidates (RPC1, RPC2), a second distance (d2) extends between the second and third reflection point candidates (RPC2, RPC3), a third distance (d3) extends between the first and third reflection point candidates (RPC1, RPC3), and respective sensor distances (x1, x3) extend between the first or third reflection point candidate (RPC1, RPC3) and the sensor (S). It is checked (S3) if the time dependencies of the absolute value of the first distance (d1) and the absolute value of the second distance (d2) are equal, and if the time dependencies of the first distance (d1) and the second distance (d2) are mirror symmetric relative to a plane (P) which is orthogonal to the third distance (d3) and extends through the second reflection point candidate (RPC2). If this is the case, the reflection signal out of the first reflection signal and the third reflection signal corresponding to the reflection point candidate (RPC3) having a larger sensor distance (x3) is classified (S4) as a false signal.
    • 本发明提供了一种分析反射信号的方法。 由传感器(S)接收(S1)与反射点候选(RPC1,RPC2,RPC3)对应的反射信号。 对于对应于各个第一到第三反射点候选(RPC1,RPC2,RPC3)的第一到第三反射信号,确定距离(d1,d2,d3,x1,x2)(S2)。 第一距离(d1)在第一和第二反射点候选(RPC1,RPC2)之间延伸,第二距离(d2)在第二和第三反射点候选(RPC2,RPC3)之间延伸,第三距离(d3) 第一和第三反射点候选(RPC1,RPC3)以及各自的传感器距离(x1,x3)在第一或第三反射点候选(RPC1,RPC3)和传感器(S)之间延伸。 检查(S3)第一距离(d1)的绝对值和第二距离(d2)的绝对值的时间依赖性是否相等,并且如果第一距离(d1)和第二距离 距离(d2)相对于与第三距离(d3)正交并延伸穿过第二反射点候选(RPC2)的平面(P)是镜像对称的。 如果是这种情况,则将与具有较大传感器距离(x3)的反射点候选(RPC3)对应的第一反射信号和第三反射信号中的反射信号分类(S4)为假信号。
