In order to study the influence of deep seabed environment on acoustic propagation characteristics, a deep seabed terrain model is established. The BELLHOP model is used to simulate the acoustic propagation characteristics of different seabed terrains under the sound velocity distribution of deep seabed acoustic channel. The differences of acoustic propagation characteristics under three typical deep seabed terrains of “mountain”, “basin” and flat seabed are quantitatively analyzed when the receiving depths are 500 m, 1 km, 3 km and 4 km, respectively. The physical interpretation is carried out by using the propagation and time arrival structure of the intrinsic sound line. The research results have guiding significance for the combat use of sonar equipment in deep seabed environment.
