A system (10) and method for interrogating a plurality of different environments to locate an object within the environments includes a plurality of transceivers (14). A control unit (12) is also provided to selectively operate each transceiver while it is positioned in a respective environment. For operation of the system, an identification tag (24) is affixed to the object (22), and transmission of an interrogation signal (26) from a selected transceiver is accomplished at an inaudible high frequency. The tag is then responsive to the interrogation signal to send a return signal (28) back to the control unit via the transceiver. A follow-up search of the environment can be made with a hand-held mobile locator that electronically interacts with the tag to provide for a more precise location of the object in the environment. |
