A method and system for determining a separation distance between a first object and a second object comprises using a search module associated with a first object comprising a first transponder having a unique address. The method includes using a reply module associated with a second object comprising a second transponder having a different, unique address. The method includes the search module transmitting a search signal on a first frequency, said search signal including the address of the first transponder and the address of the second transponder. The reply module receives the search signal and locally validates the address included in said received search signal for the second transponder, whereby, if the validation is positive; the reply module transmits a reply signal on a second, different frequency.
