Abstract: In the shallow ocean waveguide, seabed reverberation is the main factor contributing to reverberation. Due to the waveguide effect, seabed reverberation in the time-frequency domain can exhibit a stable and regular interference structure in shallow water. However, this interference structure is significantly affected by seabed scattering, which makes it difficult to accurately extract the regular interference structure of the reverberation. In this paper through conditional generation of adversarial networks, simulation modeling and experimental verification, the relationship between different seabed acoustic parameters and regular interference structures in reverberation is analyzed, and the effect of rough seabed scattering on these structures is discussed. The results show that seabed substrate parameters such as sound velocity have significant influence on the value of reverberation waveguide invariance, while the interface parameters can also affect not only the observation of regular interference structures, but the reverberations intensity as well. When interferometric fringes are recovered by using conditional generation adversarial networks, it is found that the selection of short-time Fourier transform time-frequency parameters can affect the recovery result. Preliminary studies show that the recovery result reaches well when the signal determined time-frequency parameters are matched with those of rough seabed.
