Identification of Source Location Based on Compressive Sensing and Wave Propagation
In this paper, a new approach to identify the source location is proposed by exploiting the compressive sensing (CS) theory, which indicates that sparse or compressible signals can be recovered using just a few measurement.A simulated finite isotropic plate with some piezoelectric actuator and sensor is studied.Piezo electric actuator placed on the plate is used to xcite a narrowband frequency waves.Consider reflection and dispersion, the signal which is received at only one sensor contains many components.The location of sensor is known, and the source location need to be identified by using the received signal.Based on the wave propagation properties, the proposed approach to get different distances from sensor to the mirror points of actuator by minimizing the 11-norm of the sparse matrix in the discrete spatial domain.Then, the location of actuator is obtained.The simulation study shows the proposed method achieves a high level of localization accuracy.
