On the Application of Adaptive Signal Decomposition to Parameters Estimation of Multi-target Echoes

This paper explores the application of Adaptive Signal Decomposition based on Matching Pursuits algorithm to multiple targets detection and parameter estimation in active sonar signal processing. The method can not only resolve multiple targets, but also extract more acoustic features of the target while providing estimation of its parameters. It not only brings the advantages of wideband signal into full play, but also can solve the problem of multi-path phenomena. So compared with the existing methods, this method has significant superiority. Simulation results have verified it.
