Abstract:
1. A method for monitoring structures in a vehicle, the method comprising: sending a signal having a frequency range into a structure in the vehicle from a fixed transmitter associated with the structure, wherein the signal has a selected frequency range that encompasses all frequency ranges used to monitor the structure in the vehicle; receiving a response to the signal at a fixed sensor associated with the structure; creating a transfer function using the response to select a set of delay coefficients and a set of weight coefficient for the transfer function, wherein the transfer function simulates responses to input signals having frequency ranges encompassed by the selected frequency range; inputting parameters into the transfer function to simulate sending the signal having the frequency range into the structure by the fixed transmitter; responsive to inputting the parameters, receiving a simulated response that simulates the response received by the fixed sensor; determining, by a processor, whether the response matches the simulated response; and generating a warning indictor if a match between the response and the simulated response is absent.
