SECURITY COMMUNICATION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide the security communication equipment with high reliability by utilizing a very high frequency radio wave (nearly 100GHz) in which a narrower beam angle is set than a visual angle of a telescope with a conventional magnification. SOLUTION: While the operator 3 catches a communication opposite party visually within a visual field of a telescope 1, a beam axis of a transmission radio wave from a millimeter wave transmission reception unit 2 fitted integrally with the telescope and a reception radio wave from an opposite party is coaxial with an optical axis of the telescope and a beam angle of the radio wave is smaller than the visual field angle of the telescope. Security communication with the opposite party is secured within an environment where the relation above is established while disturbance from others is excluded.
