Correlation study of sea spikes using purely numerical simulation

The sea spikes in radar echo lead to serious interference for marine targets detection, which is aggravated at low grazing angle (LGA). To investigate the relation between sea spikes and sea surface events, a multi-physics based numerical model is established. The results confirm the strong correlation between the sea spikes and breaking waves on the sea surface. The wide-band back-scattering characteristics of sea surface evolution for different polarizations is also numerically studied.
