Modeling of First-Order Scatter from Ocean Currents Based on Distributed Source

In this paper the distributed source model of first-order scatter from ocean currents is put forward, which can describe the distributed characteristics of ocean currents effectively and be used to evaluate the spatial spectrum estimation techniques under different conditions. Then the numerical simulation of the first-order scatter is carried out using this model. The performance of the MUSIC and the generalized MUSIC algorithms is investigated with the simulated data and the influence of the amplitude-phase error of the channel is evaluated simultaneously. The results show that the distributed source model presented in this paper provides an effective way to model the first-order scatter from ocean currents.
