Simulation of Reverberation Time Series Based on Multipath Propagation Theory

摘要：

It is necessary to simulate seq floor reverberation time series for testing and evaluation of active sonar signal-processing algorithms and active sonar system-performance models. Traditionally,for an isovelocity sound-speed profile,consider simulating only the reverberation arising from direct-path propagation from the source to a scattering patch on the seqfloor and back to a receiver. Actually,the effect of multipath propagation cant be ignored. Therefore,the reverberation model based on multipath propagation theory is proposed,and a method for simulating reverberation time series is presented with the seafloor is divided into range-azimuth cell. The simulation data will be useful in the evaluation of active sonar system.
