  • Abstract:
    In shallow water environments, geoacoustic parameters are important to predict the performances of sonar systems. In this paper, a compressive sensing (CS) based spatial-temporal approach is proposed to invert the geoacoustic parameters. The channel impulse response is sparse in time domain, thus CS is exploited to estimate the arrival times of different paths, which offers a super resolution in estimating the arrival times. With the estimated arrival times of multipaths received by a vertical linear array (VLA) via CS, the geometry and geoacoustic parameters can be determined. A sea experiment was carried out for evaluating the effectiveness of the CS based spatial-temporal inversion approach. The analysis of experimental data gives us encouragement.
