Abstract
A method and apparatus are provided for locating an obstacle between a transmitter and a receiver. The method includes: determining at least one elliptical ring in which the obstacle is situated, the elliptical ring being defined by two confocal ellipses, having their focuses corresponding to the transmitter and to the receiver, each elliptical ring being associated with a physical echo generated by an obstacle; estimating a distance between the obstacle and a focus as a function of the separation between the confocal ellipses at the obstacle in a plane normal to the axis defined by the focuses so as to obtain a set of potential location zones for the obstacle in the elliptical ring; and lifting the ambiguity between the various potential location zones of the obstacle so as to deliver a location zone of the obstacle.
