Due to the severe multi-path and noise interference caused by the special ship structure and hull vibration, the existing intrusion detection methods have great limitations in the shipborn environment. Based on the analysis of signal propagation characteristics in shipborn environment, a noncontact intrusion detection method based on channel state information was proposed, which fully utilized the amplitude and phase information of the WIFI signal. Based on the difference of subcarrier sensitivity, an evaluation model of sensitive subcarriers was proposed. By screening subcarriers which are more sensitive to the environment, the environment is more finely perceived. The actual ship test results show that the accuracy of intrusion detection can reach more than 95%, which verifies the robustness and reliability of the intrusion detection system.
