An equipment security apparatus comprising a base member and a cover member. The base member is attached to vertical or horizontal surfaces by means of bolts or adhesive pads and plates or brackets as required in a particular installation. The cover member is removably attached to the base member by inserting a pair of inwardly directed pin members which extend from the cover member into holes provided therefor in the base member and locking the cover member to othe base member. Equipment is securely attached to the cover member by means of one or more U-shaped rod members or straps which are made from case-hardened steel so as to prevent their being readily cut or severed by manual cutting apparatus such as bolt-cutters or the like.

A broadband transmitter element, located at a remote object, transmits a broadband signal at a prescribed transmission time. A broadband receiver element, located at a base platform spaced from the remote object, receives electromagnetic radiation during a reception search window. The broadband receiver element stores information characterizing the broadband signal. A synchronizer synchronizes the broadband transmitter element with the broadband receiver element for timing the transmission and reception. A processing device derives an estimated time of flight for the broadband signal to travel from the remote object to the base platform, and a correlation detector, located at the base platform, identifies the remote object and the arrival time of the broadband signal by correlating the stored information with signals received during the reception search window.
