Patent ID: 7937248

Claim:
A method for monitoring structures using virtual time reversal signal processing, the method comprising: sending a signal having a frequency range into a structure in a vehicle from a fixed transmitter associated with the structure to form an original transmitted signal; receiving a response to the original transmitted signal at a fixed sensor associated with the structure to form a received response; reversing the received response to form a reversed response; processing the reversed response using a transfer function that includes one or more first delay coefficients and one or more first weight coefficients empirically derived for the fixed sensor and for a plurality of fixed transmitters including the fixed transmitter to simulate propagation of the reversed response from the fixed sensor to the fixed transmitter to form a simulated time reversed response, wherein the simulated time reversed response is a simulation of a response of the fixed transmitter to receiving the reversed response from the fixed sensor; and performing an analysis on the simulated time reversed response to monitor for anomalies associated with the structure.
