Abstract: A method of laser scanning a perimeter zone of a target site for the detecti on of potential threats comprises: scanning a pulsed laser beam across the perimeter zone; receiving echoes from the pulsed laser beam and forming for a plurality of perimeter zone scans to form scene images. In addition, a metho d of authenticating a potential threat detected in a perimeter zone of a targe t site comprises: detecting the potential threat, interrogating the potential threat by a wireless transmission; declaring the potential threat unauthoriz ed if no response is transmitted within a predetermined time interval or if the received response is determined not to comprise the proper access code.

Abstract: A method and system are provided for authenticating a potential threat detected in a perimeter zone of a target site. The method comprises the steps of: detecting a potential threat in the perimeter zone of the target site; upon detection, interrogating said potential threat for a response by a wireless transmission; declaring the potential threat unauthorised if no response is transmitted wirelessly within a predetermined time interval from said interrogation; receiving said response if transmitted, and determining if the response comprises a proper access code; and declaring the potential threat unauthorised if the received response is determined not to comprise a proper access code.
