Abstract
A structure detection system and method for detecting anomalies associated with the structure are provided. The system includes a first transceiver, a second transceiver, and a processor. In a first TR test, the second transceiver receives a first probing signal sent from the first transceiver and performs a time-reversal (TR) process to generate a first TR signal to be sent to the first transceiver, and a first channel state information (CSI) is obtained in response to the first TR signal. In a second TR test, the first transceiver receives a second probing signal sent from the second transceiver and performs the TR process to generate a second TR signal to be sent to the second transceiver, a second CSI is obtained in response to the second TR signal. The processor compares a combination of the first CSI and the second CSI to a reference CSI for detecting anomalies.
