METHOD AND DEVICE FOR PASSIVELY ASCERTAINING A POSITION

摘要

The invention relates to a method for passively ascertaining the position of an object, having the method steps of ascertaining bearing data, wherein the bearing data includes the direction of the object and the point in time of the bearing, and two different types of bearing data are ascertained, namely acoustic bearing data and visual bearing data; storing the bearing data; identifying bearing data of different types as belonging to the same bearing; calculating the distance of the object from the time difference of the points in time of the bearings that are identified as belonging to the same bearing; and calculating the position of the object from the direction and the distance of the object.
