1. A method for determining a position of an object using at least one acoustic emitting-receiving sensor comprising the steps of:
- emitting a signal from said at least one acoustic sensor toward said object, said signal comprising an emission cone of waves;
processing received waves for detecting only the waves at an edge of said emission cone of waves which have been diffracted by an edge of said object; and
determining the position of said object with respect to said at least one acoustic sensor based on said detected waves of said emission cone of waves.

Abstract
The present invention provides a method and device for determining the positioning of an element or target using at least one acoustic emitting-receiving sensor. In this method only the signal received by said sensor and due to the diffraction of the signal emitted by said sensor is taken into account.
