INTRUSION DETECTION DEVICE, INTRUSION DETECTION SYSTEM, INTRUSION DETECTION METHOD, AND INTRUSION DETECTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent a detection possible area from becoming small in a configuration in which intrusion of a person is detected in a predetermined area using an electric wave.;SOLUTION: An intrusion detection device 102 detects movement of a person in a predetermined area to which a radio signal is transmitted from another device. The intrusion detection device 102 includes: a reception unit 52 having an antenna and receiving a ratio signal with the antenna; a space feature amount calculation unit 11 for calculating space feature amount in a predetermined area on the basis of the radio signal received by the reception unit 52; and a detection unit 82 for detecting movement of a person in a predetermined area on the basis of the space feature amount calculated by the space feature amount calculation unit 11. The reception unit 52 is capable of selecting a directivity pattern of the antenna and selects a directivity pattern with which a level of a radio signal to be received is the smallest from a plurality of directivity patterns.;COPYRIGHT: (C)2013,JPO&INPIT
