Random phase screen model of ocean turbulence

Webb13 dec. 2024 · To explore the propagation characteristics of VAW under the effect of ocean turbulence (OT) and the impact on imaging, the phase screen method is used to simulate the propagation of VAW generated by a phase-modulated uniform circular array under the effect of OT and the imaging of the target. Webb1 mars 2013 · A new model for turbulent phase: the sparse spectrum (SS) random field, which offers substantial reduction of computer costs for simulation of the wide-band random fields and processes, and is capable of generating long aperiodic phase "ribbons".
