A system (1) for determining the position (d) of a wanted object (BKn) which is positioned in a row (2) of objects (BK), said objects (BK) being each provided with a transponder (TR), characterized in that
- a left transmission coil (9) is provided which is arranged at a left-hand end of the row (2) of objects (BK), and in that
- left scanning signal generation means (12) are provided such that said left scanning signal generation means (12) can supply a left scanning signal (INTnle) for triggering a response signal (RESn) of a transponder (TRn), with which the wanted object (BKn) is fitted, in a first step to the left transmission coil (9) with a left scanning signal (Ile) having a starting value (Ii), and through which subsequently the left scanning signal (INTnle) can be supplied to the left transmission coil (9) with current strengths (I2, . . . , I1+1, Ii, . . . ,Iz) changed in steps, and through which a change in the left current strength (Ile) in accordance with a minimum current value difference is achievable, and in that
- left detection means (15) are provided such that it can be ascertained whether the transponder (TRn), with which the wanted object (BKn) is fitted, has given off the response signal (RESn) triggered by the left scanning signal (INTnle) supplied to the left transmission coil (9), and in that
- left current strength value detection means (18) are provided through which a value V(Ii) can be determined of that changed left current strength (Ii) of the left scanning signal (INTnle) with which after a change in the left scanning signal (INTnle) was supplied to the left transmission coil (9), and in that
- a right transmission coil (10) is provided which is arranged at a right-hand end of the row (2) of objects (BK), and in that
- right scanning signal generation means (13) are provided such that said right scanning signal generation means (13) can supply the right scanning signal (INTnri) for triggering the response signal (RESn) of the transponder (TRn), with which the wanted object (BKn) is fitted, in a first step to the right transmission coil (10) with a right current strength (Iri) having a starting value (Ii), and through which subsequently the right scanning signal (INTnri) can be supplied to the right transmission coil (10) with current strengths (I2, I3, . . . , Ik+1, Ik, . . . , Iz) changed in steps, and by through which a change in the right current strength (Iri) in accordance with a minimum current value difference is achievable, and in that
- right detection means (16) are provided by means of which it can be ascertained whether the transponder (TRn), with which the wanted object (BKn) is fitted, has given off the response signal (RESn) triggered by the right scanning signal (INTnri) supplied to the right transmission coil (10), and in that
- right current strength value detection means (19) are provided through which a value V(Ik) can be determined of that changed right current strength (Ik) of the right scanning signal (INTnri) with which after a change in the right current strength (Iri) in accordance with the minimum current value difference the right scanning signal (INTnri) was supplied to the right transmission coil (10), and in that
- position determination means (24) are provided through which the position (d) of the wanted object (BKn) can be determined from the knowledge of said value V(Ii) of the determined changed left current strength (Ii) of the left scanning signal (INTnle) and from the knowledge of said value V(Ik) of the determined changed right current strength (Ik) of the right scanning signal (INTnri).
