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

摘要

PROBLEM TO BE SOLVED: To provide an intrusion detection system, an intrusion detection device, an intrusion detection method and an intrusion detection program capable of preventing a detectable area from being small in a configuration for detecting a person's intrusion in a predetermined area by using a radio wave.;SOLUTION: An intrusion detection system 201 comprises: a transmitter 101 which is placed in a predetermined area and transmits a radio signal; and a receiver 102 which is placed in a predetermined area and receives the radio signal transmitted from the transmitter 101, calculates space feature quantity in the predetermined area on the basis of the received radio signal, and detects a person's movement in the predetermined area on the basis of the calculated space feature quantity. The transmitter 101 is capable of selecting a directivity pattern of the radio signal, and selects a directivity pattern with the smallest level of the radio signal received by the receiver 102 from among a plurality of directivity patterns.;COPYRIGHT: (C)2013,JPO&INPIT
