1. A wireless communication channel monitoring system using cooperative jamming and spoofing to monitor information transmitted and received through a communication channel set between an illegal transmitter and an illegal receiver possessed by users using wireless communication for malicious purposes, comprising:
a spoofing relay to amplify and relay an illegal signal detected from the illegal transmitter according to a preset amplification coefficient;
a cooperative jammer to transmit a jamming signal for changing the quality of the communication channel to the illegal receiver with a preset transmit power; and
a monitor to calculate the amplification coefficient and the transmit power so that the monitoring amount of information is maximum based on the illegal signal received from the spoofing relay.
