Simulation of transient scattering from ocean surface with ship wake

A time domain integral equation (TDIE) based procedure for simulation of transient scattering from ocean surface with ship wake is developed. First, the simulated surface is generated by using the ocean power spectrum and the ship spectrum. Smoothing technique is used to handle the truncated boundary. Then the TDIE method is employed to extract the backscattered signatures. Doppler spectrum is analyzed by using the time domain echoes. Numerical examples are provided to validate the proposed scheme.
